I hope that the pictures and info have helped you devise a plan on how to record the piano. What I really want you to do is to just get out there and start experimenting - that's the only way you are going to get good at something. Someone can tell you how to do something, but to really become and expert, you need to struggle through it yourself. Then you'll know the ins and outs.
Make sure you have the right gear. If you need something, go back to the first page of this article and checkout the gear we recommend for recording piano. If you click the gear links on the first page, you can get more info at Musician's Friend. Don't wait - buy what you need now - you only live once is what I tell myself. Get a nice pair of mics - it will work on many different sources, and will last you many years of high quality recording.
Good luck, let us know how it goes, and see you next time!
