Bushman,
Welcome to the 'darkside'! Ha!
Or as we in the hangin crowd say, the 'enlightened' ones.
I'm just kidding guys, so all tenters don't start throwing stones. HYOH or SIWYP (Sleep in what you prefer).

10ft apart is probably not enough. As Lori said, 12-15ft is better. I try for 5-7 paces (about a 32in stride), so you just have to figure out what works best for you.

I have a double layer hammock so don't have the sliding, pad issue.
One of my other hammocks is single layer and I have a neat sheet sleeve that I can slide a pad into and either suspend under the hammock, attach with safety pins, or place inside the hammock.
