As dozer said, get yourself the big halfords kit. The halfords "pound through" screwdrivers are a good buy as well.
The propshaft socket is great, have a look on ebay for one of those.
Also a 52mm (I think) impact socket for the hub nuts, much easier than using a box spanner and a lot more professional than using a hammer and chisel!
A long breaker bar to use for wheel nuts is better than having to jump up and down on the tyre spanner supplied with the truck too.

Edit: the way I read it the OP was just asking what tools are good to have. Obviously you don't need to carry all of my suggestions with you everywhere! I only carry the breaker bar fitted with a 27mm socket.
