When I was using the saitek x52 throttle (now using CH pro throttle), I had the profiler set it up like this:
Scroll wheel button was Shift, scroll wheel did nothing; Hat switch was coolie, shifted was slew; E was autopilot (left throttle button); D was close speedbrake, shifted was open; the I wheel was set with bands for the boat switch; I was CMS press down; mouse button was PAC; mouse hat was set with bands for china hat, shifted was mic switch
Since you just bought it, you may not have understood any of those controls. I recommend you spend at least a couple days getting comfortable with the Warthog's basics before you try mapping buttons. Mapping axis' however is of course a must do.
I'm pretty decent at using the Hog's systems, so if you have any questions I'll more than likely be able to help you out.
