This doesn't apply to you, unfortunately, but a character with at least 14 levels of Paladin can take their Holy Sword spell generated weapon with them when they TR. Just make sure that you cast the spell (maybe even a few times if you want a Greatsword and a Maul, etc) and get your TR done quickly so that the Holy Sword doesn't evaporate while you're doing your TR character building (you get more than 15 minutes, though, so if you have a plan written down, you should have no problem).
The biggest things that I'd suggest for your particular situation is to start with an 8 Wis (6 if WF) and don't worry about missing out on spells since you have absolute crap for spell points at level 4-6 anyway. Once you hit level 7 and eat a +2 Tome, you'll have all the wis you need with Tome + item. I'd actually make the exact same reccomendation to a pure Paladin, by the way.
The second thing that I'd reccomend comes in two parts - you don't have enough skill points per level to take care of traps, so don't even bother. Since you aren't going to take care of traps, don't worry too much about Int. a 10 Int is nice so that you don't have a penalty to your skill points, but any point going to Int is a point that isn't going to Str, Con, Dex or Cha.
You need 15 Dex +2 Tome to take GTWF. You need 14 or preferrably 16 Cha to take the Divine Might line to a decent level. You need 14 Cha so that you don't die in a light breeze. That doesn't leave a lot of points left for Strength and Int even in a 34 point build, so don't put too much into Int.
My last thought is that the last two Rogue levels you took might be nice, but level 4 Paladin spells are amazing. Holy Sword means you don't have to craft Greensteel for any raid bosses and you can always summon up a Holy Sword Maul to take Skeletons apart without bothering to craft a Pos/Pos/Pos weapon. Also, Zeal is an absolute delight. Doublestrike is not quite as impressive as the 10% speed boost used to be, but a double Smite is a thing of true beauty.
I've heard rumors that 4th level spells beyond Holy Sword and Zeal exist, but I don't think they have much credibility.
