Laptop  
Laptop is great, but has 2 problems:
(1) Battery is so dead it won't recharge. So I have to rely on the natty but rather precarious magnetically-retained power lead connection. It disconnects very easily if the cable is disturbed, and when it does, the battery being useless, POW - everything goes. Apparently this will cost me about £100 - for a new battery - and the new one may only last about 2 years of active service. This is hard to accept. I wonder if the old one can be taken apart and just the non-proprietary but functionally most important bits (I'm thinking of the rechargeable cells themselves) replaced? It would need a small, asterisk-ended screwdriver....hmmm
and

(2) Although it instantly found the wireless (router/network) when we reinstalled OS X 10.4 etc, it knows about this other computer*, despite trying to share files, the two can't see each other directly. So there's stuff for me to work out how to do.

* = I know this because the second time I used it, it realised it had the same name as the first ("'s computer") and told me to change it, which I now have, thank-you "'s laptop".

Batteries - you have 2 options. An apple battery will set you back a premium, the one in my powerbook was still producing usable oomph after 450 cycles. You can get 3rd party ones that are noticeably cheaper and noticeably rubbishier, in which case eBay is your friend. Lithium Ion batteries prefer to be used hard rather than cooked, so it is likely your laptop spent its former life plugged into the mains and the battery never really got exercised hence its complete deadness.
Torx screwdrivers aren't actually necessary, you can manage with a flat bladed one usually, or just have a look down the pound shop for a set of torx ends. As for replacing the innards, I dare say it's possible, but you might need to think carefully because you are packing a heck of a lot of energy into that battery and lithium ion cells are a touch delicate. I don't know how the power management circuitry in the battery would need to be reset or adjusted to deal with cells that are of a different origin/capacity to the ones originally provided.
You might want to have a look at this but you chemist types are all trained in explosive handling right?

Awesome! The pyrotechnic possibilities had occurred to me but I wondered if there was something modular and robust inside the pretty casing. Actually, there is a third possibility in Apple selling reconditioned batteries from time to time, but that might involve buying online (meh) and last time I looked there weren't any being offered anyway.
