I ordered some stuff and some of it is being delivered to my house. A few other things are for pick up at the store. If I'm driving down to this store for pick up can I just get my pick up inside the store?

Yes.

Yes, I believe so. Go to the customer service desk and show your order #. The pick up area is right next to customer service

They complicate everything

Yes as long as you have you reciept to prove it's your pick up and your name with your id proven your identity to matching your ordered I believe it gets sent to your email when you have made an order for pick up

No they have a pickup parking only for pickup you just park and let them know you are there.
