Preheat oven to 175 degrees C or 350 degrees F. Boil salted water in a large pot; add pasta, and cook until
al dente. Then, drain pasta, and set aside. Melt butter in a large skillet over medium heat, then add most of the garlic, keeping some for later; coat the garlic completely with butter. Now, add shrimp, and toss to coat. Remove pan immediately from heat; shrimp will not be cooked yet. Sprinkle the shrimp with breadcrumbs and transfer the entire mixture to a medium casserole dish. Pour wine and the lemon juice over the shrimp; cover, and bake at 350 degrees F or 175 degrees C for about 10 minutes. Then remove cover, and bake for another 5 minutes. Heat olive oil with remaining garlic in a small saucepan and toss the pasta with the olive oil and garlic mixture. Finally, serve the shrimp over the pasta with additional lemon slices on the side.
