Don't. Sweat. It.
It can not be over emphasized how approachable the whole thing is to new shooters. The guy I was working with on the line was a new shooter with no courses or training under his belt and he did fine. He struggled a touch with some of the manipulation but I didn't think anything less of him, we all had to start somewhere (others were focused on their own thing anyways and paid little attention to other shooters on the line).
If you want a leg up, I will again plug ATS which is holding a CQB shoot prep day Sunday the 26th of January. Claude who runs ATS will help you sort out manipulation, gear set up and help you figure out your sight offset close in. We are really lucky to have ATS and Skills and Drills locally: affordable coaching from good people.

For those of you who might not have had the benefit of formal training/courses, let me breakdown some skills/drills you should know:
-Load/Unload
-Stoppage drills (how to clear "jams"*):
-Bolt/slide fully forward
-Bolt/slide to the rear
-Bolt/slide Partially to the rear
-Mag Change:
-Tactical load
-Emergency reload
-Shooting positions:
-Standing
-Kneeling
-Urban prone (for when the weather gets dry)
And finally figuring out your sight mechanical offset on your rifle/carbine.
All of this can found online easily. Practice will help, some coaching/feedback will be better. (Only perfect practice makes perfect!)
* Please avoid the use of the word "jam". While you can do whatever the fawk you want in the grand scheme of things, using proper terminology does help communicating effectively with other people.
