First problem is instance variables and structs. Most of my app mem
use is many instances of small objects or c arrays of rather small
structs. I wouldn't want to inflate my memory use that much but I'm
worried about penalties in accessing 32 bit integers inside structs. I
also feel really strange using NSUInteger for things for which even a
32 bit integer is too much.
I would say that if time and motivation allows :-), pick an
approach, implement it, profile, and adjust. So if you find that
NSUInteger works, and the memory usage is within reason, you can
stop there. And if it's not, you can pick a smaller data type
for your structs, re-test, and see what the performance penalty
is, if any, and if necessary decide whether it's memory usage or
performance that's more important.
Otherwise you'll drive yourself crazy wondering about the
what-ifs and never get anything done. :-)
Good luck,
R.

Someday I'll look back on all this and laugh... until they
sedate me.
