1.I want to know is there anyway of mending my headlight or will I need to buy a new, as you can see-the left hand side doesn't sit inside it's case properly:

2. Is something wrong if my car is VERY unresponsive in the low end?? Especially from idle, even if I put my foot to the floor in neutral, the revs climbs very slow. When I pull away at the lights, the car seems to struggle or hold back and never pulls off cleanly. I have already cleaned the throttle body, had the clutch changed, got a new air filter and spark plugs on. Once past about 2k, it's fine and very strong.
Any suggestions/advice welcome,
Cheers
Ant
