Is it okay to break every baby shower etiquette rule there is?

I am 37 weeks pregnant with my first child and I am a bit of a control freak these days. I am having a baby shower but apparently I am breaking every etiquette rule there is and I'm starting to get nervous about it. I am very shy about people staring at me so I decided to have the shower after my little girl is born so all the attention can be focused on her and not me. I am throwing myself a baby shower (broken rule #1) in a hotel banquet room with catered food (broken rule #2) and I making it a come and go as you please event (broken rule #3) and not opening gifts at the shower so people are not staring at me for a couple of hours while I do it (broken rule #4) and we are privately storing the cord blood stem cells and adding money donations to the process as part of the registry (broken rule #5). So I am really going out on a limb and I'm sure to offend some guests with one of these choices. How do I make the atmosphere really happy and entertaining to distract from doing all these things that make me happy but not my guests?
