BG2 has only one official expansion, ToB, although a few of the mods are big enough to count as an expansion in their own right.

NWNs generic weapons are good, there are every base type and enchanted versions. The artifiact weapons are OK as well, nothing that stands out as much as Celestial Fury or the Equalizer though, but that could just be because I havent analysed NWNs selection to the extent Ive analysed BG2s and am just not perceiving the best of em for what they are.

You can have two henchmen in the HotU campaign. But NWNs engine dosent allow for the same control as BG2s, having henchmen can be more of a hindrance than a help, and a full party of 6 would be unmanageable.
