My car came with 195/50/15's and I have no problems with comfort.
but for weight saving I would have thought 13's are the way to go

A big consideration if you are going v8 is your final drive ratios. There are some gear ratio calculators on the net
This may be a decider on your wheel and tyre choice ( rolling Circumferance ).
It certainly assisted in my tyre and wheel choices.

very good point and should be easy to work out if you decide on a nice engine rpm in 5th, say 70mph @ 2000rpm with a v8

Diff: another linky
standard cossie RWD's have 3.64 diffs (7.5"
4x4's have 3.62 diffs (7"
I don't know the LT77 ratios though 
but I know that most people with a V8 rush seem to want 3.14, 3.36 or 3.38 diffs(but they mostly have 15", 16" or 17" wheels)

Lt 77 were ratio's I belive cant confirm as I am running Getrag gearbox
Lt 77
3.321 1st
2.132 2nd
1.397 3rd
1 4th
0.77 5th
the reason the V8 boys ( like me
like the 3.14 is the need to get 70 mph as low rpm in top gear as possible for cruising . Especially if you have a cam that has a tendancy to want
to let large lumps of air in on anything abve 3.5k
even with my 3.14 setup 1st gear is left for showing off  .
