In arena, likely 4x Enhance Shaman plus healer of choice.
In battlegrounds, likely 4x Frost DK plus healer of choice.
Ellay is mixing the two, I believe 3x DK, 1x Enhance and 1x Resto Druid...
For PvE, pretty much any tank + any healer + any three DPS.
A lot of people have non-standard combinations that are fun.
If your goal is mostly world pvp and/or large scale battlegrounds (EotS, AV, IoC), almost anything is going to work somewhat.
If you're playing two or fewer classes, you can optimize fairly well.
Playing three or more classes, makes it rather hard to do well.
I've enjoyed 5x Feral & 5x Resto, 4x Warlock with 1x Priest, 4x DK with 1x Holy Paladin.
With a melee team, you need to have Click to Move and Interact With Target.
CTM is in mouse options.
IWT is a keybind in Targeting Functions.
You basically spam a priority sequence for your DPS.
And also spam your IWT.
Mine is set up like this:

I use Grid Custom Layouts, for an alphabetical sort... so it is the same on every screen.
And have a Repeater Region, sending my clicks (within the grid area) to my healer.
Who interprets the clicks, via Clique.
