Here at sea level, the APC 9x6 seems to give the best times with the TT36 for quite a wide variety of planes.
 
Personally, with a new ABC engine, I do my first test flights with one inch less pitch than I expect to end up with (eg. 9x5).  My thinking is that letting it run free will help with the final break in, and then as I increase pitch, the stopwatch will tell me if in fact there is improvement.

Here in Dallas we run mostly reverse rotation engines, and mostly on suction. Out prop choices are limited compared to "normal" props, but we are satisfied with the results we get. We use the APC 9x6 pusher for 36, 40, 46 engines. For 60's, it varies by engine. On the OS 65 VRDF, the APC 10x6 pusher is fastest. On the rear intake Webras, the APC 10x7 pusher is fastest. On the front intake MVVS 61, the APC 10x8 pusher is fastest. I have tried Graupner and Zinger pusher props also, but the APC's are decidedly the best.

How does the Webra 32 compare to the TT 36, power wise and carb function?

I ran a box stock Webra 36 on 10% with an APC 9x6 and could go 90 mph. Unfortunately, the airplane was a dud so I sold it, and later sold the engine. I don't know how much performance difference you would see between the 32, 35, and 36, but the 36 ran fine with the stock carb, and I think the 32 and 35 probably use the same carb. Alas, more engines they don't make any more.
