Temple of the Elemental Evil + Scourge of the Slave Lords + Qeeen of the Spiders

[Evilhalfling]

I have a later version of GDQ1-7 that starts with a tie in to the slavers, its an ambush by a 1/2 drow and a surviving slave lord or 2 -
since i don't have/ never ran the slaver series I'm not sure how well it works.
the module also names the various drow hanging out with the giants, and gives them house / clan affiliations.

The A series plays pretty well in 3.5 but you'll have to step down the XPs substantially to keep PCs from leveling out. Mook humanoids abound and yet are still worth substantial XPs even though they'll die in droves.

The G series, which I'm running now, seems to run much better on the standard XP awards.

But T1-4 is likely to be the bigger problem. I haven't run it in 3.5 but I think characters will rocket well out of A series levels before they're done.
I'd also recommend editing T down substantially. If there was anything wrong with the module in general, it dragged on too long. I was working on an edit for my Classic Module Campaign but ended up skipping it entirely. I'd cut out the 4th level of the dungeon and the elemental nodes completely.
