Hi jado,
1) When playing live with PT, do you always use a click track? Also, what sound you use for the click? What do you use, eight notes?? Does it differ from the click you use in the studio? Also, is it loud or buried in the mix?
Many of these questions have been answered before please try the "SEARCH THIS THREAD" link at the bottom of my signature. Not every song has a click - usually just the ones that have a film (which needs to be in sync) or a sound that we can't make in a live situation (like a heavily processed drum loop for example). I use the same click in the studio and live. Here is a link to the exact sounds I use..

2) From a technical standpoint, who triggers the pre-recorded tracks, and therefore the click? Is it you?
Yes I start and stop them from a remote USB keyboard.
3) Finally, how does a touring drummer makes money and how does it differs from a studio musician? Certainly, I do not want to know specific amounts, but I wanna know how is the "money flow" for working drummers.
Yes you can make money as a touring musician such as a share in the fee that the venue pays (from the ticket sales) and the profit from the merchandise. BUT the expenses can be unbelievably high - so sometimes the profit is nowhere near the amount you might have estimated.
cheers
