How common would stuff be breaking? Also, any suggestions for other cheaper upgrades...Building on a small budget..

I am to.

It wouldn't break that much, mines pulley swapped, and it's doing fine right now, if your only gonna do 20 with it you shouldnt need to modify much, exact the steering maybe and new belt and pulleys

Isn't a 6-7" to 3" overkill? If he want 20mph idk.

A 1:1 pulley ratio will be more in your range for speed. Maybe make the front an inch or so bigger. Id go with a 4" or bigger rear.
