How to become an online reseller?

[HC5831]

I'm interested in buying some computer goods at a discount and selling them on ebay for a profit. I would like to do some research on all the things I should look into before I start this. Can anyone point me in the right direction?

I have the discounts locked up through an employee discount, so making money is not the issue. I'm more interested in details. ie insuring items, requiring a signature, using paypal, warranties, legality etc.
