Daanji,

If I may offer up my 2 cents worth.. Start by looking through the Macro Compendium. It's an awesome resource for macros for every class. And my personal suggestion would be, whether boosting or questing, begin learning your macros and abilities NOW. I run a mixed class team, and the learning curve for all the different abilities and spells, plus the timing and coordination of them, can be very steep. Even if you need to modify the macros due to a lack of lvl 80 talents or spells, it's better to start using them and practicing now, rather than wait until you are 80, and realizing you can't clear a single instance. It can become rather frustrating.

Also, as far as your group makeup goes... I would STRONGLY recommend changing your hunter from marksman to survival. I ran my hunter a marksman until very recently, and until you hit very high gear levels, you are going to be disappointed in his DPS output. Survival will give you better DPS until he gets geared up.
