how to store pricing (anyone have any helpers for price data?)

You typically want to use decimal with currency fields because you can/will lose precision in a float field. Plus, floats make it harder to do simple comparisons after doing calculations since you might end up with 5.49999999 instead of 5.5.

Here is a nice reference I found:
