Congrats!!! It's really awesome that yall are making sure great progress!!
Here's my input on what yall you be doing
Yall might want to have driver tryouts since yall have the extra time. By doing tryouts, you know who you want on your drive team, and then you have them practice until the wheels fall off of the robot
Don't stop brainstorming! Every time your team is together, have them take another crack at bringing up a new idea to make the bot even better.
I hope yall do well!! It's always promising to see other teams so far along in the process
