Everything everyone has recommended would be in place of stock. For example if you are going to replace the camshaft and lifters, why not put a slightly hotter/more aggressive cam in its place? If you have to bore it out (bad cylinder walls) why not stroker pistons and rods?
If you are trying to keep cost down and can get by with just a hone and rering you could still go with a better cam and pick up a little more power.
Just take your time and think things through and you'll be fine.
