Hi BladeM3,
First & foremost don't worry, what you are going through is no different to what a lot of us experience (and some don't but they're the lucky ones, the rest of us are just normal).
There is a lot to take on board and there will be times when you walk away thinking how badly you've done & other times when it's absolutely great. The big thing is not to compare yourself with other people but do what you feel comfortable with in yourself.
BTW - I still get confused on the radio, so I would suggest you don't worry about that one for now. I was several hours in when the instructor told me to simply enjoy it, for flying is fun. Don't worry about things, enjoy yourself and it will come together.
