I agree looks good,solid start!
Like you said about the forks they need replacing,if you look thru eBay and such like you may find some rockshox mag 20/21 will need a 1 1/8 diameter steerer tube plus anywhere between 7/9" of tube length (depending on frame size)
As for rims/hubs well the choice is vast!! Mavic/araya plus many others,hubs shimamo or a more exclusive brand hope/ringle/bullseye!
Depends what your budget is etc
Ps,half the fun is trying to root out a bit of retro gold that's why it's so addictive,few months ago I had 1 bike (gt lts2 now I have a rts1 and a rts2 from same year one part done other not started!!!) enjoy!!
