I'm a fully farmed nuker... And, I'm actually quite done... So I figured I might share some stuff... Enjoy!
Here are some tips that I hope can help:
Leveling:
Lvl 1~60 if possible go garment and spear...
and besides doing quest, farm only on Magic using monsters... It's the fastest way and I believe it maximizes your potential...
1~20 is easy... Just about anything...
20~30 Farm in Ravine Gun Powders/Earth Magicians/Taoist
30~40 Kill Scorpions and Dark/Red Eyes from Dead Ravine...
40~50 White Spiders would be great...
50~60 Ishades/Hashades/White-Faced Spiders/Sonars/Planars/Big White-Faced Spiders
60~70 would be different though... You might want to stick with Spear+Armor or go for Swd/Shield+Armor...
GARMENT IS NOT AN OPTION untill you get to about 67+ and be able to cruise through Nachals...
PVP:
Just remember, your role is a range damage dealer... So I suggest melee skills to be the least of importance
PERSONALLY b/c some people might think otherwise.
Anyway, 1v1's might not be your forte... It might really be frustrating against Pure Strs but well, don't feel all that bad... You still got so much more edge such as faster leveling/faster sp farming/KSing ability(Piss the shit out of ppl), etc... LoL!
Skills
I strongly suggest Fire as main nuke and Lightning as sub nuke... AOE spells would be your best PvP/farming buddy or sometimes bad! Pfft!

But anyhow, with the status immunities the new aclhemy provides, it'd be really pointless to get Ice nukes.
As far as the usefulness of some skills, such as the Lion Shout Series and Weapon skills... Well, if you have SP to spare, go for it. Shout is a great finisher and weapon skills are just fun to watch!
Here's my Skill Hotbar
Buffs
All I can say is... Every bit helps
Alchemy
Hehe... The last thing you want is to get your nukes cancelled, it's enough to deal with stuns and knocbacks/knockdowns... SO I EXTREMELY SUGGEST TOTAL COLD IMMUNITY! and if possible, all status immunity... (I am

)
Critical Parry Ratio would be nice on your shields too! (Try not to play around with shield too much though, at one instance I lost 19 block and went to 10 with my old shield using a 10%AttrAssim Pdef Inc Stone and boy it was a bitch to upgrade back up!) And if you can increase your parry or hit ratio further, it would be a great help.
Also, a no brainer, STAMINA and INT/STR stones. Save and use every bit of them!
Word of caution : Unless you want other stats to change while doing your alchemy, ALWAYS use the 10% Attribute stones and beware of anything more than that.
Lastly I suggest that you don't try increasing any stats that are already about (+33% and above). Trust me... It's not easy! Alchemy can be a bitch!

Not here to tell everyone how to play b/c you're probably here for the same reasons I do -- To have fun... So feel free to experiment around and try everything out. Be sure to save some money for Skill reallocation potions though.
Last thing I want to say, hmm, to maximize your potentials, pay real close attention to the things you lack, i.e. HP and Defense
Well, just so if anyone would be curious, here's my build (Currently) :
31 Swd/60 Spear/68Cold/68Ltng/69 Fire
