Since this is your first time, I would recommend doing them straight at lower temps, so you get a feel for how they cook. Then you can adjust your methods with foil, etc. on later cooks based on your straight-through cooking results.
Pretty much ditto for me. Most racks I get aren't super beefy so I just cook straight and sauce last hour of the cook. I generally cook 250-275 range so I can get them done in 3-4 hours but nothing wrong with a nice low and slow cook.
