For patterns to tie probably best starting with the basics
Pheasant tail nymph
Gold ribbed hairs ear

Personally i would avoid any hackles till you get the basics down.
I always find ebay is top class for buying small items like threads,wires,hooks and other small stuff.
Most of the time you get free delivery
If you buy your hooks in small numbers id go for ebay, you can get 25 kamasan hooks for £2 posted.
But if its in bulk you can get them cheaper elsewhere.
But for capes i would avoid ebay as much as you can.
Fly Tying Materials from Funky Fly Tying have some top stuff
