Wizard/High Wizard Build Advice

[azurerogue]

My current wizard build is not the greatest (I'm aware of this fact), so what I'm mostly looking for is advice on making my High Wizard better when I rebirth.

Currently, this is what I have on my wizard:

STR 1+1
AGI 9+4
VIT 1
INT 90+9
DEX 42+5
LUK 1+1

I've stopped working on INT and am now going for DEX. I originally planned to have 99 INT and 89 DEX base at lvl 99, but I'm thinking it might be wise to switch those (even though I'm not going to PvP much until after rebirth). My skills currently are:
Sight 1
Napalm Beat 1
Cold Bolt 5
Frost Diver 10
Stone Curse 1
Fireball 5
Firewall 10
Fire Bolt 10
Lightning Bolt 4
Thunderstorm 1
Jupitel Thunder 10
Waterball 1 (still leveling it)
Stormgust 10
Earth Spike 3
Heaven's Drive 5
Quagmire 5

Now, I know there are flaws in that, so rather than paying to reset I'm just going to try to live with it and level to 99/50 and fix the problems when I rebirth.

Here's what I'm looking at as my final stuff after Rebirth, please give any advice you can (nicely).

STR 1
AGI 1
VIT 40
INT 93
DEX 99
LUK 1
(all base, with no job/equip bonuses)

Skills:
Increase SP Recovery 5
Napalm Beat 5
Soul Strike 7
Fire Bolt 4 -> Fireball 5 -> Firewall 10
Cold Bolt 5 -> Frost Diver 10
Lightning Bolt 4 -> Thunderstorm 1
Stone Curse 1

Jupitel Thunder 10 -> Lord of Vermillion 1 (just for hit-locking purposes)
Waterball 5
Icewall 2 (extra points, I wasn't sure where else to put them??)
Storm Gust 10
Earth Spike 3 -> Heaven's Drive 5 -> Quagmire 3
Soul Drain 10
Magic Crasher 1 (I have yet to usefully utilize this skill, but I think it looks like fun)
Amplify Magic Power 10

(note, some Wiz skill points went into mage skills)

I appreciate any advice. Also, for the poorly equipped solo wizard, is soils the best place to stay until rebirth? I like the money I make there from generic drops and such, and the exp isn't terrible (though 1.5% per kill is starting to get boring ;p)
