I find a rack of .25 works well for one table. Or if you don't mind a few extra chips, a stack each.

You really want three primary denominations in play. For you, that's quarters, dollars, and fives. NO TENS. Chips should be at least 4x the next lower denomination. I'm a fan of $20 chips, tho' I know I'm in the minority (I like to use chips that correspond to real printed/minted currency).

Your numbers are generally good, though. Since I use racks, I like nice even stacks of 20. For a one-table game, I'd do this:

140 x .25
260 x 1
80 x 5
20 x 25

That's only a little over a grand on the table, though.
