Put the bolts back on and the airfilter and pumped the gas pedal which resulted in gas leaking out at the back on the right side.
Noticed there was one more gasket in the kit -- one with four big holes in it -- I added that, and the gas leak stopped. Then I am being told there should never be two gaskets - one on top of the other (although one sort fits inside the other actually).
I am obviously no mechanic but try to fix things if I can. Can anyone give me some guidance? Thanks.

You have two gaskets fitted, that is not the way to fix a leak at the manifold.
Either run a gasket with compression limiting washers and/or fix your warped throttle body, like the pic patrickt posted above.
Or warp your throttle body further and break the baseplate mounting ears off.
You say it leaked out the back after you pumped the pedal.
Where would it be leaking from if your rear barrels are vacuum actuated, no accelerator pump?
