No point now in changing you're IP or using a different computer, the accounts are already linked. Basically in your case, if one account goes down they both will. So try not to get suspended on either accounts.
If everything you're doing is legit and there's no reason for Paypal to limit you or eBay to suspend you, it should be fine. Meaning authentic goods, SS# attached to Paypal, invoices, supplier details, etc. My brother and his girlfriend are doing the exact same thing you guys are, only they are using 3 accounts on one computer. They use different web browsers for each account, I'm not sure why but, it might help.
They do however, sell a different niche of items on each account. They've been at it for a couple years now with no problems so, you could very well be safe.
