Good points. I also simply can't recommend anyone playing TW2 directly without playing TW1. Hell even TW2 starts with certain armours and swords from part 1 and there are a few instances where dialogues and character attitude changes according to your saves from witcher 1.
I liked TW1 and controls were not bad just had to get use to them,story wise it was fine and glad I played through it until the end (actually 4 times).
TW2 was easier in many ways ie controls improved and you knew some of gerald's background and characters from TW1 so that made it easier.
Would I recommend playing TW1 first before 2,yes I would since I don't know why some people found it boring because it was not.
I can understand the control issues but as I stated just takes a little time to get use to them,also remember its a RPG so not a 5 min game ,you have to put the hours in if you want to reach the end,its not a dumbed down console game where you are finished in a few days.
Also some things were better in TW1 then 2,for example cats eyes potion in the dark.
Last point TW1 does not really take off until chapter 2 and also some people found the part in chapter one too hard(boss fight) and quit ,so at least get to the main town first and do a few things there before deciding to drop the game,personally its one of those games where you just need to stick with and it grows on you.
