Take a look at this thread. There's some good advice on there. However to go over it again, my advice would be as follows:
Set of nuts 1-11
Set of Hexes 3/4 of the larger ones
4/5 Quickdraws a mix of 18cm and 25cm
4 'Slingdraws' (

2/3 locking krabs
2 x 120cm slings
1 x 240cm sling
1 x 400cm cordlette
Don't bother with cams, they're expensive and it's harder to tell a good placement and easy to place them wrong. Once you've got up the grades a bit more, you'll have a better idea of their use.
plus all the usual stuff, harness, helmet, belay device, nutkey, prussic loops etc etc
Here is the UKC article -

Buy which ever brand/make/model you like the best. Or choose them on weight. Just remember the really small lightweight krabs can be annoying when fitting lots of clove hitches on them.
