You can get a weight set, bench and power rack. If you can't fit a rack, a lot can be done with a weight set, but certain moves aren't perfectly safe.
With just a weight set you can learn to power clean, do front squats with decent weight, zercher squats http://www.youtube.com/watch?v=tq1maZuQTgI jefferson squats/deadlifts. Can also do floor press or put some planks and books under yourself to get full range of motion.

What kind of weight set, power rack, bench to buy you can discuss in equipment forums like http://forum.bodybuilding.com/forumdisplay.php?f=26
Spinlock bars suck though, low weight capacity and annoying to use.
