I must admit the commands are relatively crappy. Now I'm in skeleton mode, and pressing Z only changes the bone : can't get back to normal body.
Edit : nevermind, that's solved.Also, how the hell can I spin the camera ?
The controls for Blender can be tricky sometimes, and usually are when you first try to do something (but that's how all new tools are I've found), but I find that its controls make more sense to me then 3ds Max or Maya. Though I couldn't, for the life of me, figure out how to snap things to the grid. Thankfully it's easy to simply type amounts for translations, rotations, and scaling. ([g][y][.][-] to move an object -1.6 units along the y-axis, in case people don't know)
To snap things to the grid, just hold control. Control can be set to either do magnetic snapping or incremental snapping, which can be toggled with shift-tab. I think that in this file it's set by default to magnetic snapping, because it makes it way easier to align blocks precisely.
By the way, I've added torches and chests and furnaces and the like now.
