Well, I used this thread and some others to help me decide on this trio during the 20% refurb sale:
EF-S 17-55 f2.8
EF 85 f1.8
EF 70-200 f4 (non-IS, shooting kids sports outdoors in sunny Florida)
I know it doesn't sound very impressive against everyone's dream list that costs $10k+, but I'd say I did alright for $1.5k and got 95% of the performance those lists offered.
Excellent lenses, you are in for a treat!
+ 1 on the kit (almost like mine) I would recommend picking up the 50mm f/1.8, it's super cheap but very discreet (as opposed to the 17-55 which tends to scare people - or maybe its me!) and great for kids. I find the 85 a bit long on a crop body for indoor stuff.
