It seems a shame to have all that MND gear and then not to finish it off with a (White/Red Cape +1 3MND & Reverend Sash
2MND) but you've certainly got plenty to spare. xD
HMP is probably your buddy on the way up, obv your bigger hmp items come in later but you might be interested in picking up a (Salutary Robe
/Salutary Robe +1) for +1/+2 hmp.
The only piece of gear I really recommend picking up is an Apollo's at 51 for consistent Repose lands. (provided you skill up divine magic, obv)
WHM is just one of those jobs innit xD, given its core roles in an xp party it can practically do the job naked; but having a strong enfeeb set/hmp set (and maybe some -enmity & mp) certainly doesn't hurt. xD
