I'd say to do a little homework on what the scope in the package is. It wouldn't take long to get a number of opinions on this forum concerning its quality, durability, etc. If it gets bad reviews here, then I'd definitely go with a separate scope. The sling is not a major expense, so if the scope isn't a decent one, it won't cost that much more to get a good sling.
I agree with superpig on starting out with reduced recoil ammo. Not that an '06 produces a huge recoil, but as a beginner, it would be good to start with something less than full power.
