Part of what might drive your choices among the many good one's you've gotten so far are time, work space, and what "some money" really means. If your primary intention is to drive and enjoy, then the starting point is making it safe and reliable. That can be done without engine suspension changes. If your primary intention is to have something to be working on all the time with having a fully modified (at least mechanically) result, then the major suspension changes and driveline replacement is the way to go............assuming that "some money" is a good size pile. Or if your primary intention is to have something neat to drive recreationally that you can do a number of small changes each week or so while still having it be useful in between, then the suspension modifications based on the stock Ford stuff is the way to go (which would be a car similar to the one in the craigslist ad I linked earlier).

To those ends here are some resources to stimulate your thinking process and give you direction on budgeting. Keep in mind, any of the major component choices you pick are just a part of what it will cost to get the job done. For example, if you pick the Posies Indadirt front suspension "kit" that will get you most of the way to a dropped, driveable car, but you should plan on another $100 or 2 to allow for having to do other things you'll find while changing parts; maybe fasteners, tie rod ends, etc. etc.
