The second two are all in Catalan, though, which might make it more difficult for you.

However, limit the amount of time you spend on courses. You need to be immersing yourself in the language too: watch TV3 on Youtube, listen to Radio Catalunya online... doesn't matter if you don't understand, just get used to hearing the language. Also, get yourself a copy of Learning With Texts (http://lwt.sourceforge.net/) and start importing Catalan news articles and the like into LWT. Reading is a great way to improve on a language.

Also, find some Catalan speakers here to exchange with. Seriously. reading, and writing/speaking with other Catalan speakers helped me much more than any website.

Bona sort!

If you are a beginner I would suggest this course: http://www.intercat.cat/speakcat/. Some have already recommended parla.cat, which is a very useful resource I would also encourage you to use.

If you live in a relatively big city, check if there are any Catalan Lectureships nearby: http://www.llull.cat/catala/aprendre_catala/aprendre_catala.cfm. Even if you are not a student, you might be able to attend the classes for free as a "guest student". That will depend on the university and on the teacher, but you can give it a try.

Depending on where you live you might be able to find a Tandem partner, which is also normally for free. Even if you live in an isolated place, as long as you have Internet, you can find a Pen pal who wants to do a language exchange or just help you in your learning process.
