Some of this requires knowing which year(s) car and transmission.

1. You will need both transmission hangers (Mounts)
2. 987 axles take different speed sensors the sensor pre 987 picks up pulses from the outer surface. The 987 has the magnets on the face towards the bearing
3. 6spd axle splines are longer, so as you mentioned the bearing carrier will have to be changed.
4. 2002 and earlier transmission hubs on the 6spd take 10 mm bolts. The CV Bearing has a 10.1 MM through hole. The 5spd flange has an 8mm thread, and the CV bearing hole is 8.1 MM diameter through hole.
5. The 2003 and up axles have 10.1 MM diameters holes in the CV bearing for both 5spd and 6spd, but the 5spd still uses an 8mm threaded bolt, which has a shoulder to make the through size 10mm. You can get around this by drilling and tapping the axle flanges to 10mm (I have done this as a fix to stop breaking the bolts)
6. 5 speed axles are different lengths shorter than the 6Spd on the driver side and longer than the 6spd passenger side.
7. A 5spd clutch disc has a smaller pitch diameter spline, the same number splines, but a smaller pitch. so the disc's are not interchangeable.
