Just my 2 cents... For indoors, I've been living on 28mm F1.8 (mine is a very good copy (@F2, not so much @F1.
, I bought a new one, just manufactured 2012...) + 50mm F1.8 (very good even @F1.
for quite sometime, 1 flash, 1 led lighting (or another flash), umbrella, remote and light stand/holder. If you're not going for branded names, you can get all of them for under $1K. I'm using Yongnuo, Nissin and local branded (Malaysia) strobist accessories. They're cheap but still offer good quality accessories. For outdoors, you can try Tamron 17-50mm F2.8 (VC or non-VC). Non-VC is cheaper and sharper but doesn't have stabilization. VC is better all-around. For tripod, you can get the cheapest manfrotto or jusino (if available). You can just replace them later based on need.
28mm F1.8 - $450-500 (you may want to replace this with the 17-50).
50mm F1.8 - $100
Nissin flash + batteries/charger - $200
