I found Benjawan Poomsan Becker's books (and recordings) very helpful.
I also found Teach Yourself Thai, by David Smyth to be be very good, and there is a lot of dry humour there --- For example, a conversation between an expat and a taxi driver where the expat has to explain that he doesn't have a Thai girlfriend, but a farang wife...
In either case you should have the recordings.
I also like these sites: http://www.thailandqa.com/forum/forumdi ... rning-Thaihttp://www.learningthai.com/
Once you have a basic grasp of Thai, this site is great for aiding translation of stuff you find on the Internet (e.g. when people post in Thai on Facebook...) just cut and paste the Thai text... http://www.thai2english.com/online/
From the learningthai site there is this delightful book from the 70s, "Manee and friends": http://www.learningthai.com/books/manee/index.html
If you are talking to Thai people around 40 years old they will remember that book from primary school...
I found it a very effective way to approach reading Thai script.
The great thing about Thai and most other East-Asian languages is that for basic usage the grammar is very simple --- once you know some nouns and verbs you can just throw them together, no worries about cases, tenses, etc, as you can see in the first Manee lesson where you learn:
"X has eyes"
Getting your head around the tones can be tricky. However, it might help to understand that tones are not
just a matter of "musical pitch". They are also distinguished by emphasis on different parts of the syllable.
Watching Thai movies with English subtitles can also be helpful in developing a feel for how the language is actually used. You can order DVDs and VCDs from some Thai sources, but nowdays you can also go to youtube and search for
"thai english subtitles"
This safe-sex add is a nice example... https://www.youtube.com/watch?v=bz99gWfA0eE
And here are a bunch of songs with Thai and English subtitles... https://www.youtube.com/watch?v=UIMb1N_ ... sults_main
