Is it possible for you to take any classes? I just finished Japanese 101 at my university, and the way we started learning was by listening so our sensei, and having things written in romanji (using the alphabet) as well as practicing how to write in hiragana. I think japanese would be really hard to teach yourself, so at least taking a 101 class will really help. If you want to try on your on, I suggest learning how to write hiragana first, because that will help you read it.

pimsleur is good if you only want too speak some and understand, but if you are serious then you should take courses or get a teacher here at italki and buy the book genki, very good book

There are many materials on the net, and lots of books in stores. Try to gather good learning materials. A good introductory book (or Ebook) would usually have a method to learning the basics of the language. That's where you start. Try looking for a good website or something; just use Google. Reading, writing, speaking practice, and Kanji IMO are the main concerns with this language. We should learn them all simultaneously, little by little.

I hope you don't mind me sending you these links, I think they can really help you. mms://mediam1.gpb.org/gpb-Education/2006/GPB-ED_IJAP215G_000000_151020815.wmv and mms://mediam1.gpb.org/gpb-Education/2006/GPB-ED_IJAP217G_000000_151020822.wmv and mms://mediam1.gpb.org/gpb-Education/2006/Irasshai_IJAP220G_000000_151020844.wmv
