Need help updating characters

[Arstortuga]

I don't get to play much, so I'm not going to have time to build a character up to 8th level before the stones of experience expire. However, I feel like I should take advantage of them. So, I do have two eligible characters, and I'm trying to decide which one of them to use a stone on. I also have a +5 lesser reincarnation stone that I could use, if needed, on one of these characters.

I've played quite a few different characters over the years (been here since headstart, just not much of a forumite), but I tend toward sneaky and/or TWF, so with that in mind, I have:

Drow Ranger6/Rogue4
Elf Fighter 8

Any good builds out there that I should be going into?

I did a little work in the character planner, using my 8th level fighter and a +1 reincarnation shard to get rogue in at 1st level (actually I forgot that I was going to have reincarnate, so my ranger levels are 3-8 in this planner, but I think I'll leave those as fighter and get ranger levels at 10-15):

I took a bit from the Blitz and Monster builds, but my idea was to pick up in defense, with the dragonmarks, some of what I lost in DPS. Longswords because I have a few, but I could easily go with scimitars as well. I assume that stunning blow and trip will be strong damage mitigation, moreso than sunder will improve damage, so I focused on those as well.

I do have one specific question - am I better off with the UMD as I have it, or should I be trying to put a bit more into balance? I like UMD, but I never remember what the marks are that I should be aiming at.

More generally though, any huge flaws that people see? Anything that would significantly make this better?
