When I first started TNG I just looked up a list of the best episodes from season 1 and 2 and watched those then went straight to season 3. After I finished the show and loved it, I went back and rewatched seasons 1 and 2 fully. So that's a good option if you just wanna get to the good stuff quicker, and each episode is (for the most part) it's own self contained episode so you don't miss much by skipping parts of seasons 1 and 2 IMO as long as you watch the good episodes.

I'm on break at work so I don't have time to find the list I used but sure you can find something easily with a Google search or someone else here might recommend the best episodes of those seasons.
