First off, you're putting way too much oil in the engine. With a new filter, the 3.3 only takes 3.5 quarts of oil.
As for shocks, that's an easy bolt on replacement. If you're going with a 3" suspension lift, there's plenty of writeups on the web on how to install one. As you get closer, I can point you to links I've written on installing a suspension lift on a Frontier. There are also several companies that sell them. Consider this before buying new shocks - the rear shocks will need to be longer.
I like Ranchos for reasonably priced decent shocks. Rancho 5188s will fit your front stock or lifted. Lifted, 5116's will fit the back.
If you do a suspension lift, look at upgrading steering components as well, as the stock stuff will become problematic over time with a lift.
