Soy borracho means "I am an alcoholic". Estoy borracho means"I am presently under the alcofluence of incohol." If you say the former and mean the latter, people will think that you just do not understand the difference.
Pimsleur mostly hawks the short phrasebook things that might serve to teach you a few useful phrases and a lot of stuff that is not likely to be useful. They will teach you how to ask questions, but the odds that they will teach you to understand the answer people give to your questions are quite small.
Paul Pimsleur was a French professor who died many years ago (in th2 1960's). He was a clever chap, but the people selling stuff under his name make a lot of silly claims for their programs that are essentially nonsense. What is best is any method that uses a computer than can record your voice and allow you to compare it with a native speaker. When Pimsleur was alive there was no such device available. Rosetta Stone is a good program but it is grotesquely overpriced. I have seen it in yard sales priced at $10-$20.
Neither Pimsleur nor Rosetta Stone are the likelty to be the best value for your money. Spanish language programs are usually revised every two or three years, and the trick is to buy last year's version (for Windows 7) at a bargain remaindered price, since the new version (for Windows 8) was just released. The new version typically sells for $79.99 and the remaindered price will be around $29.99. Check the reviews given on the Amazon website. You will need a headset with a mike. These are not expensive at all.
I spent 40 years teaching Spanish, and am familiar with these programs in general, and no, I do not hate Pimsleur at all (as the ads his promoters claim), but the guys who sell programs under his name are to language learning as Bose is to stereo systems: lots of hype and high prices.
Spanish is a lot easier for English speakers to learn than English is for Spanish speakers: English has 42-45 different phonemes (sounds) and Spanish has 21-23. Spanish is spelled logically and nearly phonetically, and English, is not.
Anyone that claims that you can learn a language without learning grammar and syntax is full of beans. You may not learn it consciously, but you need to be aware of different grammatical patterns or you will sound really funny and/or not be understood. There are four basic language skills: speaking, understanding, reading and writing, but probably the hardest will be understanding the answers to your questions, rather than asking them.
