Yes, that's true about the 2-handers. IWD2 required me to alter my weapon choices.
The quality of magical weapons is about the same between one- and two-handers. There's no Greataxe of Flame here. IWD1 weapons tend to have less secondary abilities than some of the weapons available in IWD2 (especially HoF), but the power balance between IWD1 weapons is quite even.
2 characters using two-handers is about right (although I hope your bard isn't using its melee weapons much: a bard is THE support character, not much of a damage dealer in and of itself). If your druid is using spear (not staff), you will eventually find some excellent, non-random drop spears.
Edit: I have never found a magical buckler. However, Fighter/Druids can use metal armor and shields, which is just one of many reasons to favour a F/D over a straight druid.
