Let's be specific on the "seafood" thing. (I'm a fisherman's daughter, and these mixed-up terms are driving me nuts.) Anything that lives in water, fresh or salt, is technically seafood, but they are NOT all the same, nutritionally speaking. They do all contain omega-3 fatty acids, though.
Fish (has a tail and fins) is generally good, though these days it is wise to limit consumption of pelagics. (These would be deep-water predators, such as shark, swordfish, bluefin tuna, etc -- the really big fish. Because of their position near the top of the ocean food chain, their flesh can contain relatively high concentrations of mercury.) Freshwater fish usually don't have the mercury issue as long as they come from clean water, but pay attention to the fat content. Farmed catfish is dirt cheap in most parts of the US, but its fat content is a tad high for fish.
Some Shellfish (esp. crustaceans) have higher cholesterol than fish, and for this reason you should not eat them in really large amounts if you have cholesterol issues. However, they are extremely low in saturated fat, and small amounts are not usually harmful unless your cholesterol is *really* high. Raw oysters are risky for anyone with a compromised immune system, because they are magnets for cholera bacteria, but oysters, clams, mussels and scallops are quite low in both fats AND cholesterol. Very few people in the US have a habit of gorging on shellfish, because it tends to be pretty expensive unless you can buy it right off the boat. (Which I was lucky enough to be able to do for free for many years! Thanks, Dad!)
One other thing: if fish (or shellfish) has a "fishy smell" that you can detect from further away than about 2 inches, you shouldn't be eating it, because it has gone bad. Fresh (or fresh-frozen) seafood will smell faintly like the habitat it came from; either salty or a little bit muddy. Always rinse fish thoroughly in fresh water before you cook it. When buying fish, look for specimens with clear, shiny eyes -- if the eyes look cloudy, the fish has been out of the water too long. If you buy it pre-filleted, smell is your guide. If you buy thawed previously frozen fish, you should cook it the same day.
I'm going to toss in a cookbook recommendation here, one that I've spoken of many times. The Trim & Terrific series by Holly Clegg has a lot of simple recipes, including a lot that contain seafood of all types. (And yes, she even has desserts in these.) Dietary notation on her recipes is extensive and very accurate. For some samples, see www.hollyclegg.com
