I would recommend either the crossbreed super tuk deluxe like others have recommended as well. You could also check out stealthgearusa they make some great iwb as well. The advantage of the stealthgear holster over the crossbreed is its cooler to wear in summer and there really isnt a break in period were as the leather takes a bit to form and break in. Other then that they are both great holsters.
On the belt situation a good stiff leather belt like you have will work. But a good leather belt that was made specifically for carrying makes a huge difference. Crossbreed makes some great gun belts that are worth every penny.
