1- The only explanation I can think of (apart from a 'noob' crack, but I'm above that) is that the hit boxes are a little weirder than the previous versions. It is a common complaint about the game, that people who think they're awesome get killed too easily so they say the game now has no skill. I don't know, I'd think being easier to die would mean harder to not die, which means taking skill to live through a round... but that's just me.
2- Small crosshairs seem to look the best and look to offer the most precise shots, but the color is up to you and different colors will help on the different maps. Change it to whatever is easiest to see is really all I can say.
3- Try to lower some of the graphical settings like Anti-Aliasing, your resolution, and especially HDR lighting. While not all maps support HDR lighting, it drains performance quite a bit on the ones that do.
4- If if feels too slow to aim, either click on options when you start the game press 'ESC' while you're playing which will bring up the main menu contents. When you click on options, a window will open up with tabs on top, click on the mouse tab and there will be a mouse sensitivity slider you can adjust. The alternative is if you have the console enabled, you can press the tide key (~) in-game to bring up the console where you can type the command, 'sensitivity X' (remove the two ' and X stands for any number) to do the same thing as above. Apart from that, it takes time to get better as you continue to learn how to play and develop your own style and such.
5- It could just be a visual spec error and as long as that doesn't happen while you're actually playing, then I doubt it'll really matter.
good luck and have fun,
