One thing could be to use chase cam so you can see the people around you better, and with braking, its always better to brake a little early for turn 1 and then modulate the brake, so if someone ahead of you does something stupid you have already slowed down a bit more so you can avoid the incident. What I suggest as a final thing to do is to (in qualy) practice coming into T1 with the speed you would on your first lap, and getting your braking point down so you can be confident on when you need to get on the stoppers so you don't go deep, and then brake just slightly earlier than that so you have more time.
