I made seafood linguine recently. I consulted a couple of recipe books and then did a little of my own thing. It was really easy and FAST and amazingly delicious.
After putting the water for the pasta to boil, I started sautéing some onion and some garlic in olive oil. When the onions were translucent, I added in some parsley, salt, pepper, white wine, chicken broth, and saffron.

I let that cook for a minute or so and then added in a couple of chopped tomatoes.

After cooking them for a few minutes, I added in scallops, shrimp, and clams.

I cooked it all until the clams opened and the shrimp were pink. I then added in some more parsley.

Tossing the whole thing with the linguine and adding some Parmesan cheese, we were ready to indulge.

Elías really liked it :)
