Welcome, Killa!
My advice is that you best befriend with all the folks in town, whilst building and expanding your farm. Each of them will give you their own unique benefits. Greeting and talking with them everyday will increase your relationship with them. Giving them gift will greatly boost your relationship with them, especially when you give it in their birthday. But just make sure to know what they like and not. Other than that, just try to relax and enjoy the game. You will discover many tricks as you play through.
