Lowe's is right across the highway, on Wonder World. There are a few stores over there, with a few more on the way.
A few exits south is the outlet mall. Plenty of shopping there.
HEB grocery store is a couple exits north, on Hopkins/Hwy 80 - west of the interstate (although there is a smaller one, also on Hopkins, a little closer to you).
Wal-Mart is also on Hwy 80, but it is east of the interstate. Not too far from HEB, is Target, Best Buy and a few other stores.
There are plenty of threads here about dining already. I like the Italian Garden, Zen's pizza, Craig O's pizza, Kobe, Texas Red's Steakhouse, Garcia's, the Taco Hut on Aquarena Springs, The Root Cellar, Palmer's (outside, for lunch), Thai Thai, Grins (also outside), Centerpoint Station (across the highway from the outlet mall), Gordo's Burgers and Stuff (on North LBJ) and a few others.
