http://www.gemini-tackle.co.uk/rigs.html have a lot of common rigs and a breakdown of the parts you need for each one.
not forgetting the learning zone on this site:

I find Sunset Amnesia pretty good for hook lengths, not had any knots slip yet. For rig bodys I use 50lb Ultima Seastrike XT which can be got quite cheaply.
Some 80lb rolling swivels, lead links of some descripton (breakaway fast clips are good), pvc tubing for bait stops and pennal hooks, 8mm beads and some 10mm sequins. If you doing some clipped rigs them either breakaway clips or some nice stiff wire half inched from BT and 1mm pvc tubing
I also use soft crimps to position swivels between beads.. but just nip them lightly so as not to damage the line. Some poeple prefer power gum or stop knots.
Hooks is a whole can-o-worms

I like sakuma matra for small hooks but found the larger ones bend out or snap easily. I'm using Varvias salt water champions (Veals) in the larger sizes at the moment and they seem like a good hook. Aberdeens are a good patern to have for the smaller sizes from any good manufacturor. It really depends on what suits you and your bait presentation the best.
