HDD/RAM upgrade question - 400 mhz sawtooth

Question

Hello!
My Sister has a Sawtooth G4 - Well, I believe it's a sawtooth anyway. I don't know for sure, so I'll post a bunch of specs:
It's a 400mhz model, early 2000. It shipped with a 10GB HDD, and 128 RAM. I believe it also has a 100 Mbps Ethernet. It has a DVI and VGA monitor video card, but i'm not sure the Video RAM level. It has an internal FW 400 port as well. The internal Airport card is shot - er, maybe the extension.
It has major issues with the system - and it seems to stem from a botched OS 9.2 install. It's running 9.1, but with trouble. For one, I can't open the extension manager. For two, it's slow, and acts funny.
Well, I thought i'd be nice, and try to get the G4 working for my Sister. It seems that it may require an Clean install of OS 9.0. Oh well, I can do that easily enough. However, before I go through all that trouble, I'm contemplating upgrading the hard drive (at least). With only 10GB, it's not very useful for iTunes, Photoshop, or our old OS 9 games - things she'd like to have.
I looked at the specs for the Mac at:
http://www.lowendmac.com/ppc/g4saw.shtml
It takes an 3.5 inch Ultra ATA drive? I've seen those around - and a 60GB drive or so is becoming pretty cheap. (I've seen 80G for under $50) I just figured i'd ask if anyone has tips on what to buy, how to install it, and Particularly if I need any special adapters for the G4. It does have a slot for a second internal HDD. I've also heard that a fast, second internal HDD can overheat the computer - is this a common issue I should be worried about?
The same questions go for the RAM. I'd like to add at least an extra 128MB, but I'm not entirely sure what to get. The above site mentions that it uses PC100 SDRAM in DIMM mode? Hmmm... I'll have to look around.
Please excuse any silly questions, I'm just far more familiar with more current systems, and it's 1 AM
Thanks,
Dan
PS: It looks to have a slot for a floppy drive under the DVD-ROM drive. I have a bunch of files on our OLD PowerBook 5300 that i'd like to move - but I need a floppy drive. Our old external USB floppy drive is.... very dead. The external floppy drives i've seen at stores seem to be pretty expensive, but internal drives are still fairly cheap (some under $30). How hard would it be to find/buy/install a compatible floppy drive? What format would it need to be? If such an upgrade runs over the $40-50 that a new USB drive costs, it's not really worth it.

Wow, thanks again!
I figured out that this is the AGP graphics Sawtooth - not the Yikes model. Where do these names come from?
As per upgrading to OS X - we have a G5 which she can use, and a XP box - which is down with the flu for the third (or fourth?) time. Therefore, the G4 will stay OS 9. She just wants to have a reliable machine that can play DVDs and music, and play some of our old OS 9 games. It's not intended to run any new programs, just the old ones that she can't run now. When I mentioned photoshop - it's a "Limited edition" of version 5.0 - and it's far, far, FAR more reliable on the G4 than on our 2-year-old XP box, despite the G4 running 9.1 with a wimpy 128 meg ram!
The main reason for upgrading the HDD was to make it more practical for games and MP3s - via iTunes 2! It won't play AAC, but it plays MP3s fine. She has at least 8 Gig of music - too much for a 10G drive! (Even half of it leaves precious little expansion room)
I'm watching for a "small" HDD - it seems that our local Fry's is no longer selling anything smaller than 100G - which was $100! Or perhaps they were just sold out at the time. I'll keep an eye out for another sale. In fact, asking my friend for an old drive is a good idea. They have parts from at least a dozen old windows and linux boxes floating around - so they likely have a drive or two. If it's a used HDD, loaded with Windows (probably 95-2000), will it confuse the system before re-formatting?
As per RAM:
I'm quite aware of the lack of RAM. However, I'll have to watch for sales! I'm not aware of any "Mom and Pop" stores close by, although that's a fantastic idea. A PC 133 128 MB card runs $40-50 at the local computer stores, but only $15 at OWC! Therefore, if I don't find suitable RAM locally, I'll order some. I wouldn't mind an extra 256 (or 512) for my iMac either.
Speaking of iMac - I've determined that it's the iMac DV Special ED from March 2000. (400mhz, originally 13 Gig Drive - now 60, 9.2.2) The question is whether or not it maxes out at 512 MB or 1 GB of RAM. One of the Apple support sites I found ( http://docs.info.apple.com/article.html?artnum=58007 ) said that the slot loading iMacs max out at 512. It makes no distinction between any slot loading iMac. However at http://www.lowendmac.com/imacs/dvse.shtml, it mentions that this model specifically can accept 1 gig of RAM. I'll assume that the Apple article is correct, but I'd love to get a full 650 MB if I can! (I'd love to add a 512 to the 128 I have now)
It's amazing, really - after 4 years of constant use, a hard drive motor failure (hence the 60G HDD), and a year and a half burried on a desk, the iMac is becoming more handy by the day. It's good at capturing the Video and audio from say, Halo, while my PB's too busy to run anything else (via S-Video and audio through our DV cam). It makes a great DVD player, an iTunes Jukebox, and game machine - most of my games are still OS 9. To top it off, it makes a great wireless base-station for my Nintendo DS at school, where there's no WiFi! With 30 gig of space left on the HDD, it has plenty of room for whatever I want to do with it. Guess you can "teach and old dog new tricks!'
Well, I guess this means my question is answered for now - once I find the things I need, i may have some more questions, Thanks again!
