Yeah, never change tabstop, change shiftwidth instead. I'm using these
for vim:
set shiftwidth=4
set tabstop=8
set cindent
set cinoptions={.5s,g0,p5,t0,(0,^-0.5s,n-0.5s
(similar results can be achieved with sw=2 and adjustments to the
options, but for some reason I like to think of the GNU conventions to
be based on a base indentation of 4 positions with some extra rules
where only half indentations are used)

Given an indentation of N positions we use N/8 tabs and N%8 spaces, yes.
(some authors use only spaces, so that's not a hard rule, but never
write your code with tabstops set to anything else than 8).
