Heat oil in a large skillet over medium heat, saute shallots and garlic with crushed pepper 2 or 3 minutes, stirring constantly with a wooden spoon. Add wine and reduce 1 minute. Raise the heat a bit. Add crushed tomatoes and bring sauce to a bubble. Season sauce with salt and pepper. Add clams and mussels and cover the pan. Steam until shells open, about 5 minutes. Remove any unopened shells. Add shrimp to sauce and cook until just firm, 3 minutes.
Add parsley and basil to the sauce and shake the pan to incorporate it. Adjust seasonings, to taste.
Combine drained pasta with a few ladles of sauce and pile pasta into shallow platters or bowls. Top with arranged mixed seafood and sauce. Serve with warm, crusty bread for dipping.
