Migrating Slot Loading iMac Power PC G3 Mac OS 10.4 to new iMac

Question

My 10 year old iMac has been taking way too long to start up and has been shutting down by it's self. Made the mistake of trying to do a complete back up (instead of an incremental back up) on my last back up, When that completely erased my back up drive and then failed to complete the back up, it left me with me with no back up to the drive in the iMac, I realized that I would have to actually spend money and get a new 21" iMac.
I'm just starting to figure out that the new Intel based iMac may not be able to use or read all my Power PC files. And that maybe a straight migration may not work. Here is what I have done so far.
I downloaded the "A Basic Guide to Migrating to Intel Macs". From Discussions.
I managed to download my iPhoto library to an external drive.
I tried to down load my iTunes library to an external Hard drive, but the iMac shut down in the middle of the download.
My external drive has a Fire wire 400 and Fire wire 800 input.
The old iMac has Fire Wire 400 input, the new iMac had fire wire 800 input.
I'm going to get a Fire wire 400 to Fire wire 800 cable, and maybe a fire wire 800 to 800 cable.
Here is what I would like to Migrate, in order of importance.
1.Photos
2.iTunes music.
3.Address Book
4.Pages and Word documents
Anything else I could work around or live without.
Any hints or suggestions? Should I transfer cookies?
If I cannot transfer the files from the old iMac to the new, I'm considering taking out the hard drive from the old iMac and putting into an putting it in an external drive case, then trying to download from that. What do you think?

Answer 1

A Brody;
I actually downloaded the tips earlier. That's where I found out that migrating from the Motorola Power PS chip to the newer Intel chips was not going to be easy.
Meanwhile my 10 year old iMac finally died. I tried to vacuum the inside in hopes that maybe dust was causing start up problems. When I put it back together it would not start at all. Went to plan "B" by tearing it apart again and removing the hard drive. I put it in the HD enclosure that was holding the original iMac 10 gig hard drive that I had pulled out years ago.
When I plugged it in to the new imac, it looked like everything was there. I copied photos, itunes music and all the personal files I could find.
Now I need to see if it possible to transfer play lists and book marks.
From the article I can see where to find the files I need to transfer. I can see dragging the files to the new iMac desktop. But once it get it to the desk top, how can I get the information imported to where it needs to go? Instructions are not clear on that.
The instructions say start the old mac in target disc mode, but of course the brains have been removed from the old iMac and is now a 200 gig external drive with questionable life expectancy.
Thanks.
