Okay, so I get to play this dude next time (yay!)
Necropolitan is off the table after talking to my DM.
The build now is:
Factotum 1/Cloistered Cleric 1/Factotum 4
Feats:
lvl 1: Weapon Finesse, Bonus: Font of Inspiration
lvl 2: Domain: Knowledge Devotion; Improved initiative
lvl 3: Font of Inspiration
Equipment:
Rapier +1 with a wand chamber and a crystal of return (quick draw); +1 chain shirt; heavy wooden shield; belt of healing; wand of power word: pain
Some alchemistical; forger and Rogue (lockpick etc.) stuff
I keep the three main knowledge skills, UMD and autohypnosis maxed and try to pump search a bit.
Otherwise one skill point in as many skills as possible.
The third domain gives me +10 ft. movement rate.
This should lead to a very average character who can contribute in nearly every situation and even do decent damage (power word: Pain + knowledge devotion + cunning insight) if neccessary.
The one question left is about UMD. How much sense does it make to take/max this with me being a cleric and Sorc/Wiz?
I can bascially take any wand I like and just cast the damn thing without a check. Sure, for scrolls it qould still be important, but this is a fraction of the usual usefulness of UMD. So should I just take 1 rank, none, or really keep it maxed?
Something to consider is, that our DM only hands out randomized treasures. We have no say what so ever in it and so far we never came across a "magic mart", which further limits my options.
Right now my thoughts are: Leave UMD at one rank and starting from level 8 put points in it until maxed.
Thanks in advance
