Paypal is your best bet because it guarentees that if the seller pokes out on you and doesn't send the stuff he ought, you get your money back.
As for bidding... Ebay can do it for you. Make an account, login, then click bid on this item. You have to go to the items main page for that. Then, enter the MAX amount you would be willing to pay. Ebay will then up your bid until you either win the item, or your max is beaten by someone else.
Ebay also sends emails to let you know if you've been outbid, or if you've won.
