There's apoxy sculpt, a 2 part modeling apoxy, you'd need good paints (I use some cheap craft paints) but Citadel paints work well and are waterbased as sometimes plastic doesn't like the solvents in other paints. Good brushes, mixing cups (bathroom throwaways work), stuff to store you supplies in helps too.

was is the name of the thing that most people buy to add add ons to a figure and then paint them the colour thay want,example say you were adding weight to a figure face what sort of things would you need to buy,from ebay,ie paint,etc

resin casting is VERY expensive and a pain. For something that small you'll have to spend about $400 for a compressor and a pressure pot. Dr.Deadman can help you more on that, I do all mine the old fashioned way since I do larger figures. Resin comes in 2 parts and I get it for about 36.00 for both parts and it's about the same for the 2 parts of the rubber to make the molds out of.

as for sculpting tools you'd need very fine tipped ones, which are mostly metal, and you should be able to see the wide selection at any craft shop. I don't know the names for them but there are a ton of them but for something that small you need the finest you can get.
