Ranged + Melee isn't a good choice for learning, its like jumping into hard mode. I'd suggest making a pair of easy ranged casters and play those to level 20-30 to get a feel for things.

I'd suggest that you start with two characters that are the same class while you learn isboxer.

The automatic follow you are going to get from using an addon called Jamba.

Once you're comfortable running two ranged characters, then you'll implement a melee using IWT. here is a quick introduction to the idea of IWT
