Cubic, not cilyndrical.
They're really beautiful, I like them!
My first cubic panos weren't so nice, particularily those taken at night...

I usually adopt these sizes:

Render at more than 6000x3000, but you'll need some RAM...

I usually do like this:

(Click on the first two images)
This way I can also shoot tripod bracketed nadir shots.
Some Photoshop skill required to do "invisible" merging :)

I tried both (in Photoshop), and now I prefer merging bracketed shots before stitching
them, because it's easier to shift images if the camera slightly moved between shots (wind
or else).
Anyway, if you just need to do some tonemapping (for example, replacing burned lights
with the dark shots, or taking shadow areas from the light ones), I'd do like above.
If you want to generate .HDR files instead, you'll need to drop full renders (of differently
exposed shots) into Photomatix (well, I actually never used it, so I may be wrong).
