I answered with the following for this question. If you look for tutorials for using these technologies, you should be able to get started or at least have other more detailed questions.
Two programs you should at least take a look at are Mappy and Tiled. A library for XNA integration with Tiled called TiledLib was been developed and could have bene of some use, if only to take a look at for ideas, but no longer appears to be available.
