just wanna say welcome. its late and i'll edit this post tomorrow. but go for warlocks. like hunters, they have pets to take the damage while they put on the damage. what you'll miss though, is the survivability in the beginning. but any good warlock would be able to get out of a tough jam. For a first time RAF-er, just go with two of the same. you'll start up another team in about two weeks anyway. i did a pally/lock team once and it was great. so maybe combine your two favorites and make a hunter pally team. ret isnt so bad, and the blessings/auras are great. ok its late. good luck.

edit: ok back from a short nap.... still needing my coffee. =] anyway....
if you dont like to double up classes, then try at least, two ranged characters. if one has a pet, that would be great too. like stated above, a warlock would be great. or a hunter would work as well. remember you wont have the benefit of a pet until level 10. even with warlocks, you get no tanking pet until level 10. its not too hard. i'd also pick the classes for its buffs.

i would also try a ranged/melee combo where the ranged will just stand back and nuke while the melee, preferably a tank of sorts, run in and takes the aggro. this can be accomplished in many ways. the three major tanking classes are warrior, pally, and druid. however, warriors do have it harder without much aoe tanking skills. i'd actually stick with the druid as a tank especially now that swipe has a wonderful AE zone of damage. add the increased crit% with self-heals and you're good. pallys are great too. im sure there are plenty of pally tanks out there who will explain more about them. i am not one of them, but i do like to use a druid. now for a ranged/melee combo, we also need to decide on the ranged aspect of this. do you want a warlock to DOT everything up? or a warlock to nuke? how about a mage to nuke? or a mage to AOE? or a priest to AOE? haha. do you value health regeneration more? then a class with some healing might help you better. shadowpriests are awesome for this job, or even a caster druid, either balanced or resto, but i'd pick balance. you really do not need to specialize as a tank/healer combo. you'll be burning through so many mobs that you may slow down to heal every once in a while, but you will not need a dedicated healer. trust me, even my priests combo dps way more than they heal. and this is without a tank. there's lots of things to consider, but its basically your decision as to what you'd like to play. finally on the whole class combination thing, warriors are not a dps class. they can dps, but they're not a dps class. =]

in terms of macros, you have the gist of it, which is good. what you might want to match up are the opener spells, and certain instant spells would go welll together. some spells work best with other abilities, so you might want to check those out. i cant really give you much on this as you havent really decided on a pair to play yet. you did mention you're playing a hunter and a druid for heals, and though i find that boring since i'd rather use the druid as a tank or as a dps with pet as tank, i do think you can match up some skills such as aimed shot+starfire, or arcane shot+moonfire. buff the pet with thorns, if your hunter's MM, trueshot aura+leader of the pack, and only go out of catform for heals. but thats using the druid just for heals and the aura, which is, again, boring. well there you have it. until you have some kind of plan, we cant really help you on what kind of macros to use.

there is a thread here with a list of quests for boxers, which involve plenty of non-collection quests all over azeroth. you'll have to use the search feature for that. good luck. you can even go through james leveling guide, free, to do your quests and just skip the difficult ones. getting 3x exp means having to do only 1/3 of the quests mentioned. good eh?

one last thing, boxing is not for the lazy. it is well involved and requires lots of forethought put into every combination, as well as involvement in tactics and battle planning. you will play more than just "send pet+auto shoot". if this is really what you want, play two hunters. or even two demo warlocks. but try to get involved in the game... you'll probably do a lot better and have a whole lot more fun. good luck with everything.
