Druids and paladins are two of the lowest DPS classes in the game. If IWT is working you could probably manage dungeons fine but it'll be slow, you'll have no real AoE damage or any way to CC mobs and you'll need to drink often. 1.5 gold per stack of level 45 water really adds up multiplied by 5 characters over time. You might use 2 stacks of water over an our or two in a level 55+ dungeon if you're conservative -- that's 15 gold worth of water out of whatever profit you're making farming dungeons (30-50g per run, usually.)

You probably won't be able to afford your mounts for some time. Flight paths in vanilla can take upwards of 15 minutes and then you have to wait for a boat.

I always advise a mage in your first group. Having access to a mage on one of your accounts with unlimited free food and water plus portals saves you an immense amount of gold and time when you're starting out.

My plan is to level with a mage in my group until I get all of the portals and the final rank of conjured water, then swap it out for another warlock. This way I can just summon the mage to me, fill up on consumables and portal wherever I need to go.

Moorea's composition is very similar to what I've come up with after a bunch of testing. 1 fury/prot Warrior, 2 prot/holy paladins, 1 SL warlock, 1 mage. Swapping the mage out for another SL warlock at 60. Plenty of CC and DPS. In PvP the ranged characters act like a turret, dotting everything in range and healing my warrior while I run around and kill everything. Based off the fact that I'm assuming follow is not going to work in PvP.
