I'd definitely agree with some of the previous posters. Building a simple robot that works well is a lot easier/better than trying to go the hard route and ending up disappointed. Your team has plenty more years ahead of itself to try harder robots out.
Also, don't forget the things not directly related to the robot, such as outreach, team identity, or administration/ logistics (ex. budget, available resources). It's easy to get so caught up in finishing before the deadline that other things fall through the cracks-- and teams don't operate well without handling all of its aspects.
Third, know where to find the information you need. If it's parts, know the popular websites that will have the part you need. If it's advice, work with neighboring teams. Check out previous games and know what kinds of awards and resources available on the FIRST website. Other than that, your team will pick up a lot through the mentoring process and through experience
