Sounds like your mixing a Dex/level build with a boss build. they don't really mix well from my experience but hey play the game however you want

Yeah haha...I'm trying to get an all rounder build but need to focus it more in leveling now than bossing
In that case use the skills you are now but with the change i suggested.
Defense and generally more survivablity help in leveling more than abit of extra dps in my opinion but it depends on how you lix and who you group or if you solo.
I solo lixed and personally I think getting around 3k defense on lix helps a ton, if you like the hrung helm that's okay but I suggest full DL/EDL but that's optional
Try for 5-6k hp in the tower, you should be okay for solo or if you easily stay alive cause you group or something try less
With your gear now either get 2 celerity rings to boost defense to help with leveling but you'll need to replace them when you start bossing. So if your short on gold just get another 2 valour rings now so you're using 4 of them then you're set. they're great until you can get gele sharpshot rings(if you choose to stay Dex) or necro bow ability rings(if you want a high damage inflicting boss build)
If you can get defense/heat dmg hrung braces they are great for leveling but later I'd suggest trying to get proteus braces that boost strength/Dex/vit in difference combinations but all with attack.
Or just do whatever you want

fully up to you just my recommendations
