If you just want more clearance on taller tires easy and cheap you can get 1-1/2 coil spacers for $100, '91 Ford Crown Vic shocks, flip your strut mounts and run 235-75 or 29"- 30" tires and gain several inches of total lift depending on the tires. 2" front 1.5" rear + taller tire. You could get a total of 3-4".
Boondox.com has a good before and after pic to show you what it will look like. If you want to go 31's -32's you can add a 2" bodylift for about $100 also. SKY, Rocky Road, Boondox all sell various stuff to do this. There are tons of threads on this site explaining things in detail.
Do a search on any of this stuff.
You may find this to be adequate. Systems with springs and struts and shocks are $800 and are nice but don't lift more than 3" anyway.
