Essential TT/Cartridge Set up tools

After much fretting...I've deciced to go with an VPI HW19MKIII with a Rega RB300 arm (purchased seperately) On my previous Throrens, and current AR. I believe all I used to set up my turntable was the cartridge manufuacturers template, and the basic instructions from the TT manual for setting Anti-skate, tracking force etc... What tools should I get to make sure I get everything setup right. There seems to be a wide range of scales, protractors, etc... available at an equally wide range of prices.

What really is needed and any recommendations on the most cost effecient easy to use tools?

Thanks in Advance,

Tom
