GOG and mods for classic RPGs

[Yoda]

Have a few simple questions so I thought I'd slap them all together here.

If I buy a game from GOG can I install it on more than one PC?

Are there good mods for Planescape: Torment to improve the visuals and formatting for a modern screen? Are they easy to use?

I haven't done ANY pc games since the days of Mechwarrior 2 and Tie Fighter

GOG stuff has no DRM.  None.  So you can do whatever you want with it.  Install it on your fucking smart toaster if you want.

Quick search pulls this post that features several mods: http://thunderpeel2001.blogspot.com/2009/01/planescape-torment-fully-modded.html
