I'm not sure if I saw any direct questions there...

What I have read and heard:
-3.4L 996 engine swaps have been done plenty of times with the original 5 speed transmission.
-The 987 5-speed transmission is more robust
-The VAG O1E (6-speed) and O1A (5-speed) transmissions have the same basic bolt pattern as the 2.5L Boxsters. There are lots of variants. You can look at Audi and VW Passat forums (VWVortex, Audizine, ...) for ratios and thoughts on those. -Generally they say if you hammer the gears of the 5-speed with a huge Tq spike, it will shed teeth.
