Hi James, there is another thread on here as well if you do a search. It will help a lot.
My first tools were, as follows. They are also my most used.
Jap Saw, If you cannot find a razor saw then look for a small Jap saw, or a mini-hacksaw at a push.
Mini mitre box. This will help cutting square.
Stanley knife I have found to be easier to use than the knives with the snap off blades.
Steel rulers. I have a 6inch (hardly used) 12 inch (used a lot) 18 inch (used the most).
Steel tape measure (the ones that roll up)
Calculator-you will probably add a few of you own bits so this is useful for scaling down.
Jeweler's screw driver set.
Pliers for bending wire. A cheap set of the small ones does me perfect, has long nose as well.
Needle files.
Mini vice, I have one of those that clamps to the table and the vice can be moved through any angle.
Sanding block - don't use your fingers.
G clamps - I use 6" ones to hold a board down onto the table. Smaller ones for the some gluing.
Spring clamps, to hold bits together when gluing. Buy the multi packs.
Old margarine tubs to hold bits in that I need immediately - saves them rolling off the table.
Old bits of card packaging to mix epoxy on -o don't throw away those bits of card, keep a box next to the bench.
Old boxes, small ones to to keep loose bits of wood and bits you find lying around. So if you got a new toaster for Xmas, keep the box.
All of these tools can be found in the hardware stores or B&Q, some of these like the pliers and screw drivers can be found in the bargain bins.
As Colin says, read the instructions. Sometimes they don't make sense, but if you have questions do ask on here.
Enjoy your build, don't loose to much sleep pondering build problems. And have a good 2008
