So:
1. IP Address - Can't answer this
2. Any withdrawal address I have used - Can't answer this, it's unique every time
3. Amount withdrawn - I've got no idea, maybe last withdrawal was 1 BTC? I have tons and tons of BTC transactions. If they provided me with an exact timestamp I made a withdrawal then I suppose I could find it.
I'm a little confused regarding your issues here...
1. No issues here, I doubt very many people would be able to provide their IP address from 2 years ago... That's just a ridiculous request!

2. Where have you been withdrawing your funds to? bitcoin mixing services or something? Most services like exchanges provide transaction history that should show transaction IDs and/or addresses you deposited to... and obviously all the popular wallets provide history... the only services/"wallets" that don't are generally anonymising services like mixers.
3. If you can possibly find your transaction AMOUNT for a withdrawal... surely you should also be able to find the address that you withdrew the coins to as well??!?
