Without actually seeing the hood, it is difficult to know what kind of prep is necessary. The "cracked clearcoat" indicates that it may have had a repair at some time. The cracked surface area can be the result of body plastic...and/or primer that has failed prematurely. If so, it could require some additional labor to prep for paint. My advice is to go to a quality shop....perhaps a body shop connected to a Honda dealer. Wherever you go, ask what brand of paints are used. Name brands are PPG, Dupont, Spies-Hecker, Glasurit, Sherwin-Williams, Sikkens (Akzo Nobel). Some lower shops will use anything cheaper. My experience with your Nighthawk Black pearl has always been good. Blending the tops of the fenders hasn't been that crucial....however, if you are particular and want the hood match to be "dead-on", blend them.
As for cost, it depends on the per-hour flat-rate where you are. Generally speaking, an Element hood will require about 3 or 4 hours and each fender top about 1/2 hour. So, total labor perhaps 4 or 5.....again. without seeing it, it's hard to say. Then, you'll have material cost....again, hard to say what your area charges.
Something else.....if there are any dents, obviously more labor time. Perhaps I've given you a little info that can help......I've been painting cars for a living since '67....which doesn't mean I'm the best....its simply means I have a lot of experience.......(and, I'm getting old!)
