Lane, there is literally a ton of stuff here on Mudcat to help you with learning to play leads. I was just commenting the other day over here that a good primer for learning bluegrass guitar, including leads, are the tunes recorded by the Stanley Brothers with Bill Napier on guitar around 1959.
Elsewhere on Mudcat we've talked about getting free software from the net that can be used to slow down complex passages while keeping the pitch the same. The Napier material is relatively easy and very easy to hear. You may not need to slow them down. Once you've mastered a few of Napier's leads, you'll see enough connections to start trying others or maybe even composing some of your own.
