1. if you want to be able to take credit cards, you will have to change ot a business accoutn, which means you'll pay a fee if they do or don't use credit card. If you don't want to, make sure it's clear in your auctions that you don't accept credit cards. I personally feel it's worth the cost, as I think you get more impulse buyers.
2. I use my primary account as one of my Paypal accounts, and have for years. Several feel it's safer not to. It's really about your comfort level.
3. Although I have a debit card, and I understand that you get a small portion back into your account if you use the debit account when making purchases, I get more back from another credit card I use, than I get from Paypal. So again, it's whichever way would benefit you. I sweep my Paypal account into my checking account and do all my charging using a credit card that gives me 5% toward a GM vehicle.
Hope that helped some. Good luck and much success on eBay!! It's free listing today, so it's a good way to get your feet wet (listing only is free..not gallery, 10 day auction, etc).
for now. I keep a close eye on our account so I feel I would know if something seemed suspicious. I think I'm ready to get started!!
That's with having company for several hours too! I'm ready to drop, but it's only midnight eastern... 3 more hours of listing time.... 
who needs sleep, right? LOL. At least I've got 3 bids already!

Oh well. 
I've been battling the flu and just didn't have the energy or the desire to do it. But I know it was a great opportunity. I am soooo happy for those of you who got some stuff listed! I hope you all do really well.
Ah well, at least it was free and maybe we'll get some non-last-minute bidders *crossing fingers*
