It realy depends on if you plan to tank/heal/drive or heal/Dmg and sit in back.
Most hybrids go with Mainly INT for there base stats
Gear wise you want
High str/dex (first mod) - And Int / Heal mastery (second stat)
Main slot Charm - Str/Dex (depends if you plan to hit 100+ dex for crits, or just want steady str hit dmg.) - INT and Heal mastery secondary mods.
Second charm slot - nice heals (obviously)
If you where going to tank i would use EE/Hmastery or EE/Int armor
A sweet but expensive option is high Heals with decent STR/Dex in mainslot, and having no secondary charm, but I think they would be costly

Goodluck.
