Basement insulation / finishing - my head is spinning

I've read many discussions here and elsewhere on insulating a basement before finishing it. My question is, what is the most current wisdom on insulation?

My basement is below grade, poured concrete painted with DryLoc. My thought was to glue extruded 2-in styro panels to the walls, seal with tape, build a wood stud wall, and then hang drywall.

My concern is the claim(s) about convection currents and condensation behind the panels potentially rotting my joists unless I go nuts with construction adhesive and taped seams. At this point I'm thinking I'll just paint the walls and tell people it's "industrial chic".

Seems like a lot of people here have had no problems for many years with the "old" stud and drywall technique, but I don't want to spend $$$ and time just to create a problem.

if you basement walls are not leaky, then air sealed foam is what, etc, recommends. it makes sense to me. when you build your stud wall (pressure treated wood on concrete contacts), insulate w/ roxul and use the airtight drywall approach with a vapor retarding paint. that will let moisture migrate inside to dry the wall. if you don't have a gap between the foam and roxul, you won't get convective loops to speak of. air seal like you said. that is what i'd do.
