Answer 1

The MacBook Pro 2007 specs I've found say it has two kinds of FireWire ports, one each FW400 + FW800, so if you get one cable the match would be one for FireWire400, as that one with the same plug on on both ends can work with the iBook G4, as it has the same FW400 also.
Not sure of the connector count in the FW400 cable, but since your MB/Pro has the same port too, a standard FW400 one with two plugs should be adequate to make it go. I have several of these, as most of my Macs after the 1999 iMac 400DV had the ports. So I made sure to get an external HDD with FW support, oxford-type chipset, and its own power supply; then about learning how to use clone utilities to make a bootable copy.
The real need was after I got rid of the iMac400DV after repairing & upgrading, to find it needed a new logic board; the authorized Apple repair shop botched that a bit, and tossed out a brand new HDD, and put in a used one off their bench without telling me. I had the box and receipt, but I never got my new drive back. Finally after it was repaired, I donated that computer to a salvation army thrift store in a tiny town down the road 30 miles away, along with a pile of accessories, printer, camera, etc. Because I had ordered a new iMac G4 (USB2.0) 17" 1.25GHz model from the Apple Store online. It arrived a month after ordering it, and there were glaring defects including a bent display arm, and later three logic boards and bad RAM, etc. I spent along time troubleshooting Kernal Panics that pointed to bad RAM or other logic board error, most noticable after the Apple authorized service in Anchorage upgraded the RAM. Found out it was defective after more than a month of troubleshooting at home, but the shop never did find a problem that I could duplicate in 10 minutes after I got it home nearly 200 miles. This went on for seven months. So I never really used the iMac G4 from Apple Store, but I still have it. The last time it failed, totally froze, yet appeared On. Went completely blank/dark/dead after an attempted restart. And a few weeks of troubleshooting at home, I found no leads except maybe one of the Authorized shops bungles was behind it. I drove nearly 1,500 miles taking the new iMac to-from a defective shop.
So, I have a few extra FW cords, some USB cords, and a few backup options in FW HDD(clone) and USB HDD; plus those USB flash drive things. And some dead external drives where the chipset failed. Also an OWC USB2.0 drive I've never used, in its box, since it won't boot a powerPC Mac with a clone inside. OWC wouldn't take it back or offer a tradeup plus cash to get a FW model. The OWC was a gift. No support. So I haven't bought from them at all.
I have & use a backup UPS self-filtering power supply to help against high and low grid power. Not a surge protector, as they do not work. Something with a battery inside to power the computer for at least half an hour, and automatic voltage regulation to protect against high/low power fluctuation. I also have a new spare identical unit, in the box.
Anyway, if the iBook seems too far gone, you could always look for one repaired & checked over with a guaranty of a sort from specialists who fix them for a living; wegenermedia, otherworldcomputing, and others offer models at fairly good prices. They appear to include an operating system, battery, & charger. Or see what a shop such as wegenermedia would charge to inspect and give you an estimate. Most shops have their own shipping ideas and may have a preference for a certain kind of box and packing materials. These places have refurbished models of older vintage too old for the Apple Store, but do offer repairs on various models and have many parts. You could get brave, get an iFixit guide, if you can discover the bad parts, get new ones and hope it works. Or get a repaired MacBook for under $300.
This has is a longer post than I'd planned, but it is after 1AM now and near zero, and light dry snowy outside. I was just out there a little bit ago.
Hopefully with a new FW400 cable,
you can see what happens....
Good luck & happy computing!
