Lots of good advice above, so I'll contradict some of it.
The advice about getting accessories to keep you pipe clean, such as pipe cleaners, a pipe tool, etc. is solid. A gunked up pipe makes for a lousy smoking experience.
Drying your tobacco before smoking it is excellent advice. Most tinned tobaccos have a lot of moisture added to keep them from drying out before the smoker opens the tin. Too much moisture masks the flavors in a blend. If you live in a fairly dry climate, 30 to 45 minutes is generally sufficient to bring your tobacco into a better moisture level. Experiment to find what works best for you.
Packing lighter than you think is good advice. As you get more familiar with your tobacco, you'll experiment with packing and find out what works for you. It will vary a bit based on the cut.
Since you have only the one pipe, stay away from English blends for now. English blends contain Oriental and Latakia, very pungent tasting tobaccos, and once they're in your pipe, you will always taste them regardless of what else you're smoking. As you are trying out different flavors, for now, avoid English blends until you get another pipe.
Buy a couple of cobs. They're cheap, they smoke well, and you can experiment with different families of tobacco without cross contamination.
The most popular blends are Lane 1Q and Captain Black. Aromatics make up 90% of what is smoked. Also popular are Over The Counter blends, also known as OTC's or "Codger" blends. They're generally burley based, smoke cool and mild. Carter Hall, Prince Albert, and Sir Walter Raleigh are three of the top sellers in this area. I particularly like Sir Walter Raleigh Aromatic, which has a liqueur topping. Just be aware that Prince Albert has a little Latakia in it. I'd second Carter Hall, or its clone, Chatham Manor, which is a higher quality copy.
Once you get a second pipe, then try out English blends.
Just take your time and experiment. Pipe smoking is a slow process if you're doing it right.
