2 handed weapons

[ice_magistrate]

i've looking for tips on this for some quite time now and I cant find any. do you need the feats:
* ambidextry
*two handed
* improved two wielding
to use a 2-handed weapon? I like long sword since i've got two angurvadals and blessings of the daystars maybe even a mix of angurvadals and sword of the gladiator but it's too easy. so i'm opting to switch back to dual wielding daggers but i've heard and seen that a sickle is great for hacking up ultra damage points. so do i need the feats i've mentioned for 2-handed wepaons?
I just have the NWN no expansions installed and still cant get any prestige classes so I quit on trying to get the archane archer (i liked bows but, i like playing solo, no henchmen no meat fodder). so?

Nope - all thoese feats are for dual-wielding 2 weapons.
2-hand weapons act as single wield.

I you want to use two weapons you need the above feats for a two handed weapon you dont need any of them.

The prestige class Arcane Archer is only available if you have SoU installed.
