You are going to need some rather expensive tools.  The cheapest route is to have a buddy in the trade that you can borrow them from.  Keep in mind that you will have to remain friends to maintain or alter your closet.

110 Punch Tool, $50: This is used to seat and cut the wires in the back of the jacks and patch panels.  A cheap plastic one can be had for about $7; it won't cut and it is not nearly as easy to work with, but is handy to have if you borrowed a better one earlier.
RJ-45 Crimpers, $50: This is used to compress the male connectors on to the ends of the CAT 5 cable.  Most come as combination RJ-11/RJ-45 crimpers.
CAT 5 Strippers, $Unknown: This is used to strip the outer jacket from the CAT 5 cable.  I did not have one.  I used the strippers on my crimpers, but it was designed for regular flat phone cord, not rounded CAT 5.  I nicked and broke many a wire before I got good at it.
24 Gauge Wire Strippers, $5: This is used to strip the jacket off the individual wires in a CAT 5 cable.  I used my fingernails, but recommend digging up a pair of strippers. 
RG6 Strippers, $22: This is used to strip the outer jacket, braided shielding and inner jacket from RG6 cable at the correct points to match crimp-on connectors.  About the best bang for the buck, this one is worth getting if you have any amount of cable to run.  Most come as combination strippers for other grade cable as well.
RG6 Crimpers,$40: This is used to compress the connectors on to RG6 cable.  Most come as combination crimpers for other grade cable as well.
Tester, $30 + 2 hours labor: This is used to make sure you wired correctly.  I built a single tester for all three services from Radio Shack parts and extra Leviton jack inserts for about $30, plus 2 hours labor. Here are the directions. You don't need advanced features of the $100/service store bought testers.  You only need to be able to identify which cable is which and whether any wires are crossed or broken.
Heat Gun, $15: This is used to shrink the transparent heat-shrink tubing around the wire labels.  I stole one from my wife who had used it for embossing in her scrapbooks.
Wire Cutters, Pliers, Screwdrivers, etc.
