1st gear is usually a bad idea. I'm almost always faster if I leave it in second the whole time: even if I'm down to 3k rpm. The last thing you need to think about as a newbie is shifting: your speed will come from learning the line. Read the stickied newbie guide, and the links therein: make sure to buy and read "Secrets of Solo Racing"! Also, ask a local pro (preferably someone who likes fwd) to take a run or two with you, and drive your car. They'll probably do well enough to win a class that isn't highly competitive.
