(1) There are several products on the market designed specifically for restoring black "rubber" bumpers such as Forever Black, but various tire dressing materials will work as a temporary solution. 303 Aerospace Protectant is about the best post-restoration protectant you can buy, and if the rubber isn't too far gone a couple of good soakings in 303 will renew the material to an extent and doesn't leave a shiny greasy coating.
(2) Depending on how bad the overspray is you can try a few things: First, clean the area really well. Obviously you can't really spray water in there, but try giving it a good bath with damp cloths or sponges to get the bulk of the dirt out. Once you've got the heavy stuff out get a couple of decent quality cotton bath towels and a bottle of Meguiars Paint Cleaner and "polish" the painted surfaces inside with a square of towel wet with the paint cleaner. If the overspray is loose enough to get picked up by the towel you'll be able to polish it away. There's a certain amount of oils in the cleaner that will help clean the dirt and grime too.
Paint Cleaner doesn't have any polishing compounds that I know of, the towel itself is providing the "grit" to do any polishing. You can try some products like the various swirl removers and actual polishers (with the towels) and see how you do with those. 3M Swirl Remover is a good one for that process, Meguiars has similar products. You might even try some mineral spirits on a cloth to try and break up the overspray, but I'd hate to have it effect the original paint.
On exterior paints we often use clay bars to pull overspray but I think that probably wouldn't be too effective inside, especially if it's heavy overspray.
(3) As has been mentioned, pull the plastic lenses off and wash them in diluted dish detergent to strip any old wax, grease, oil, and dirt from the plastic. Scrub away any difficult areas with a soft 100% cotton towel, rinse completely, then let dry.
Once the plastic parts are dry you can try any number of decent plastic polishes to brighten them up. Meguiar's has some Mirror Glaze products made for that which should be available at your local auto or hardware store. Novus also makes a series of very good products that are readily avaiable. If you can't find anything try going to your local airport and see if anyone is selling airplane windscreen cleaner, they might even have Mirror Glaze sold for that purpose. Any of those good quality plastic cleaner/polishes used with a good clean 100% bath towel will do a good job cleaning, polishing, and removing scratches from the lenses.
Once you've got them really cleaned well give them a good coat of wax or a polymer sealant (I prefer a non-cleaner wax like Meguiars #26, or a sealant like Meguiars #20). I've also found "Plexus" plastic window spray-cleaner leaves a nice finish.
(4) If you have some really dirty or oxidized metal surfaces use a decent metal polish like Flitz or Semichrome. Flitz is a fairly low-grit polish that does a fantastic job and leaves an anti-corrosive film on the metal once you're done. If you can't find any locally try using something like Mother's Billet Polish, or Never-Dull wadding by Eagle-One - I've even had good luck with Turtle Wax Chrome Polish & Rust Remover. Once you've got the metal shined up a good maintenance product is Mother's Chrome Polish - it's a runny liquid that you apply like a glass cleaner, let haze, then wipe off. It's not for restoration purposes but does take light oxidation off and leaves a great coating (excellent on windshields too!)
Good luck!
