Noobie questions. Don't worry though, I'll go look for a haynes manual at the weekend too

Just sourced my first Firestorm. Lovely bike in black - she's tatty but seems mechanically sound. So, Time for a tidy up.
Few of questions if I can pick the collective ORG brains.
1. Under the headlight there's a smallish square of fairing plastic that's cracked. Anyone know where I can lay my hands on another one, or what the part name/number is?
2. Anyone got a spare top yoke or some fork lowers lying around I can swap some cash for?
3. The front brake's not the best. Are they always a little dull or would a set of HH pads sharpen things up (it's running braided lines and honda pads at the moment)?
Cheers guys
