Hope you are OK.
You should be able to get a SS brake-line pretty easily. Check with your local dealer-mechanic or check the yellow pages for local fabrication. You can also go to Galfer or Russel, I am sure they'll sell you just one line.
As for the oil cooler, seems like there are some aftermarket brands that are larger and polished for "bling". You might check Dale Walker to get a lead on one. Otherwise call a bike salvage yard (800 number) & get one parted out. In fact, if you're on a budget, you might get all the pieces, color matched from salvage.
Suzuki should have all the parts available already pre-painted. I would not buy parts that weren't the right color: that paint & labor will exceed the cost of the parts, and will look worse in most cases. That Color Rite paint is very expensive & then it has to be a perfect paint job. I would advise just to bite the bullet and pay the extra upfront.
One other hint, if you have some chips or scratches, for the darker colors (like red), a flat black marker does a pretty good job of blending & hiding.
good luck. we've all been there. this is all from an earlier experience. I could go into the medical side of all this too!
