This isn't by any chance directly related to this is it?

Think you see some of my and Mercs thoughts over there.

Now if you're looking for specific build advice my first piece of advice is almost always "show me what you've come up with" as that helps figure out what you're thinking is.

If you go Stealth the two "stealth" PrCs are Infiltrator (FUCG) and Vanguard (CWCG); Infiltrator could be especially nice as you can eventually share your Stealth ability with others.  Vanguard can make a nice complement to that is it's a full BAB class with +4 FORT and can provide access to Evasion without more Scout levels.
