kurglar: I don't really have time to look into these builds in details, but I played a kind of similar build so here are my comments:
1. You need max UMD for seal-heal Your Int is probably too low to get trap skills, so drop those. If you want traps, go THF instead of TWF and drop Dex to boost Int, taking Insightful Reflexes (it also avoids wasting a level-up on Dex).
2. You really want Kensai II to be able to deal some meaningful DPS. Personally I went Fighter 12/Wizard 5/Rogue 3 (though my last level was the 3rd Rogue level, and it didn't matter since I was planning to TR).
3. Keep in mind this kind of build is more "for fun" than to be efficient. If you want to feel like you are bringing a solid contribution in high end quests / raids, that's not the build you are looking for.
