Reminder for all spellcasters and magic users: as we are in the Astral Plane, all spells and SLAs are enhanced as if cast with the Quicken Spell feat. So you essentially can cast one spell as a free action and do a normal full round action afterwards. Dunno how it is with the casting of two spells though, i.e. one quickened, one normal - as there is no "normal". I assume that using a wand still is a standard action.
