Seafood pasta

So I just returned from a very lazy shopping trip at Whole Foods (i.e. no list, no idea what to make for dinner tonight, dump random items into cart and hope for the best) and ended up buying some pasta and fresh scallops and shrimp. The idea is to make a seafood pasta in a white wine sauce. Any suggestions/ideas on how to bring it all together without overcooking the seafood?

Thanks!!

Dry the scallops thouroughly, sear them over high heat for just a minute on each side and set aside.

I'd do the same with the shrimp and add to the pasta at the end.

Cook the scallops in plenty of olive oil. Remove. Cook the shrimp in the same oil. Remove. Peel and chop the shrimp but keep the shells. Add diced onion to the oil and sweat. Add a cup or two of white wine along with the reserved shells, and reduce til almost completely evaporated. Remove and discard shells. Add cooked pasta, a lttle reserved water, more good olive, crushed red pepper and salt. And the sesafood. Let it all hang out on low for a couple of minutes. Serve.

And I'm sure all the purists hereabouts will clamor, but at the end, while things are still bubbling, I add a little bit of cornstarch (tsp or so) dissolved in 2 or 3 Tbs of heavy cream, and stir it all around 'til it thickens. And then add to the plating some chopped chives or finely chopped green onions.
