I used to play a lot, but now I get on like once a week, usually for UMS games.

Money maps are... not very fun. I'd learn how to play pro maps. =P

As for your tank problem, just how many tanks/wraiths are we dealing with here? Corsairs are pretty helpful, like devonin said. Tech disruption web too, and that can help your ground forces significantly if you place your webs right.
For ground, I'd go zealot/goon/ht. In fact, if your ground force is good enough, you don't even need to invest in corsair and let storm/goons do the wraiths for you.
