wow, that is in damn good condition!

I always loved the LC series comps aswell, got a performa 450 (aka a reboxed LCIII) on my 68k desk atm. Particularly always wanted a LC475 though

The caps are fairly easy to do, that said, if you haven't soldered much in the past i wouldn't start with good old macs. If the place in reading falls through you could always send it to me and i could do it for £10 or so.

Removing the cells is proabley a good idea as at least that will stop the cells from leaking and damaging anything

As for keyboards, the one you have there is my personal favorite, that said, i have never used the much fabled AEKII
