It has always been 40K for the level 1 training as far as I know, certainly for several months at the very least. The level 2 and level 3 skills cost something in the order of 250K and 350K, respectively.
At the moment there are a couple of "traditional" style speeder bikes along the lines of the ones in ROTJ or the one Anakin rides in AOTC. There's also the lame STAP thing that you ride upright that is reminiscent of some of the droid speeders from TPM. You don't get a full multi-person speeder until riding level 3 as I recall (not that multiple people can ride in them - yet).
