Fish,
Yes, you have to take the grill off. It's pretty easy - I did it in the Crappy Tire parking lot. There are a few philips screws and a couple of little plastic clips holding the grill on; these are easy to break, so be careful. Don't force anything. If it's not moving, there's still a screw or clip somewhere holding it on.
If you've smashed the lens, you'll have to replace the whole unit (lens/reflector). Unless you've already replaced the reflector/lens, you are currently running H4 headlamps aimed for travel on the Left-hand side of the road. It's impossible to aim these for North American driving. I just went to Canadian Tire, pulled out the lamp assembly, and went inside and found one the same size. I think it's a standard size. It fits right in, plugs right in. You'll lose the cool blue H4 beam, but at least you'll be legal and safe for oncoming traffic. Once you get the grill off, you'll see how to access the corner lights as well. They won't come off with the grill still on.
Good luck!
