the early levels are not that bad in the alliance starting areas. the Dranei starting area will see you to the mid teens. (and the storyline is not too bad either)

as for team composition, in the early stages you shouldn't need more than a couple of macros:
(tag with the pally and burn down with the shammies)

FOLLOW / FOCUS MACRO

/target leadcharcharactername
/focus
/follow

SHAMMY DAMAGE MACROS (casts on pallies target)

/cast [target=focustarget] lightning bolt

/cast [target=focustarget] earth shock

/cast [target=focustarget] flame shock

SHAMMY HEAL MACROS (heals pallies target - or pally if none selected)

/cast [target=focustarget,help,nomod][target=focus,nomod] lesser Healing Wave

/cast [target=focustarget,help,nomod][target=focus,nomod] Healing Wave
