Please help me with suspension!

I was looking through MM&FF mag for a new suspension setup. Price is very important. I found Ford racing springs all the way around for $135. This would lower the car 7/8 inch in front, and 1/2 inch in the back. I also saw KYB shocks and struts for $180 for all four. I'm guessing this is just standard ride height settup. Would these elements work together? You can visually notice my car in the rear is well lower on the left side. Do i need to worry about anything adjustable? Is this stuff I'm looking at good? Thanx a hundred million!
