You may wish to read http://www.poolsolutions.com/tips/th...pump-scam.html and do some calcs on your pump flow rate. A 2 speed pump may be a good option so that you can run on low and save operating costs. Others on the forum have the expertise in this area, I'm just flagging it as something to think about.

I'm a big advocate of using a solar blanket when heating a pool, I wonder if you have give a blanket any thought to go along with your Solar heating? My pool came with the house, and one of the best features is that the solar blanket reel is permanently installed at the end of the pool, so it is really easy to put it on and off. A lot of people I know have to either fold and unfold the blanket, or drag the reel from the side of the yard, and don't use the blanket because of the hassle. Depending on where you are on the West Coast, this may not be a big deal, but if you have some cool nights, the blanket is really beneficial.
