You've got the hat and boots already which are typically the first pick tome pieces. (Your gear shows just how non existent my group's healer drops have been this progression, literally nothing other than a sympathy weapon so far despite clearing everything except O4S from week 1 =( ).
In your situation, the weapon is likely going to be the most significant upgrade you can get at this point. Whilst the tome weapon, body and legs are all equally underwhelming, the weapon will be 3 points of magic damage and more mainstat (especially so assuming you don't also have a Twine sitting spare) which is immense all round and easily outweighs the soso secondaries.
Pps give me some drops =(
