I've heard that there are 2 different series of gearboxes and engines on the A series. So is this true?

Depending on what you mean by "series" there are many variations in the gearboxes: types of bearings; types of synchromesh; gear ratios; gear change methods; gear teeth shape, etc.
Perhaps you might mean the difference between early gearboxes with synchromesh on only the top 3 gears vs later 4 speed synchromesh?
Early gearboxes had 'A' type gear teeth and later ones were (you guessed it) 'B' type.
Engines went through a similar evolution and change over the production run of minis.

The other way to look at the question is:
direct change gearbox (pudding stirrer gear lever)
remote change gearbox (remote gear lever, and
rod change gearbox (rod change lever)

Also some 5 and 6 speed straight cut boxes were made by KG Engineering in Melbourne years ago.

Well I've counted 8 different transverse gearboxes and 2 inline in my stash. That's without any of the exotic 5 & 6 speeds!
