Toyota Repair: changing driveaxle, corolla dx, haynes manual

Question
92 Corolla DX 3 Spd Auto-Transmission 190K miles 1.6L engine

I want to change both driveaxles on my corolla and I am following through Haynes manual. There are few questons that I came up with:

1) Haynes says that I need to drain the transaxle before removing the driveaxles. Is it necessary? I am asking this as in general, it is not necessary to drain the transaxle fluid. Is this special to toyota?
2) If I drain the transaxle only then I will only need to refill transaxle withOUT doing anything to the differential fluid, is this right? Haynes manual is not clear about this!
3) It also says to remove brake caliper, bracket ad disc, which again I know is not necessary. Is this also something special to toyota construction?
3) Where to put the floor jacks? As the jacking point is already in use by the screw-jack?

I appreciate your help and will appreciate any comments and precuations that will ease the job for me to change the driveaxles.

Thanks

Answer
The differential and transmission share the same fluid, there is no seperation between them, if you drain the transmission you will also drain the differential, both are filled through the filler tube, it is not necessary to drain them, you may lose a little fluid out of the axle openings but it can be replenished once the job is done.
You will need to remove the 30mm axle nut, remove the two 17mm nuts and one bolt on the bottom of the ball joint, move the rotor and caliper assembly off the axle and tie it out of the way, then you can pry the axle out of the transmission.
Put the jacks under the lift points on the body and use jack stands for safety.
