Questions for fixing my Camry

[Ice5]

Well, I picked up a 92 I4 about a week ago now.

So far I love the car, but there are quite a few little things that need fixing.

PROBLEMS

1) Front bumper is pushed in 1/2" and is broken.
2) Driver side marker (corner?, the one outside the headlight) damaged (minor)
3) Rear center piece on trunk is kind of broken (chipped at bottom)
4) Antenna motor sounds with radio, but antenna does not move at all (currently it is DOWN).
5) Driver's door lock does not work from outside. i.e. key won't turn.


SOLUTIONS

1) I've found a new front bumper cover in Toronto. When the weather is nicer I'll paint the new cover with matched paint. Then when I take the old one off I'll pull the bumper out 1/2" then put on the new cover.

2) Ordered new marker light from ebay (is that what it's called? "Marker Light")

3) Need to buy this piece (what is the proper name for it?) from somewhere. If anyone has one for sale, let me know!

4) Do I just need an "antenna mast." How can I troubleshoot the power antenna. The mast sells for $18 USD on eBay, is this a good price?

5) I plan on getting a remote start / keyless entry / alarm unit soon. But is there anything else I can do to fix the door lock?

Thanks.
