There are always a number of excellent computer Spanish programs available. I would go to Amazon and read the reviews written by people who have used each of them. Get a program that comes with a book, and of course, buy a Spanish-English dictionary. I have not used Rosetta Stone, and comparatively speaking it is overpriced, but it could be much better.
There is less difference between spoken everyday Mexican Spanish and textbook Spanish than there is between similar versions in both English and French. The telenovelas are either Mexican or Colombian, and are seriously overacted, but they do pronounce words correctly and intelligibly, and they are free. The woman with the long dark hair is the good person. Men with facial hair are evil. Women with blonde hair, especially short, blonde hair are almost always wicked and evil.
There is a variety show on Saturday nights called "Sabado Gigante". The host, Don Francisco is a Chilean Jew, almost as old as God, but he is a jovial sort and they do a lot of nutty things. At the end of some shows, they give away a small car. Lots of really dumb games. I have been in the studio audience. It takes four hours to film one hour of content. You might enjoy it: it is like an American show from the 1950's.
