I did general relativity as an autodidact myself and may have some experience in finding resources without any help from outside. I first did SR of course. I downloaded lots of resources from the web, mostly lecture notes from various universities. Despite all this free info I found that a good textbook is an absolute necessity, so I bought:
Foster&Nightingale: A short course in General Relativity
I first did tensor calculus by studying the textbook and:
Heinbockel: Introduction to Tensor Calculus and Continuum Mechanics (only part 1) (
http://www.math.odu.edu/~jhh/counter2.html)
S. Waner: Introduction to Differential Geometry & General Relativity (http://people.hofstra.edu/faculty/Stefan_Waner/diff_geom/tc.html )
Then on to GR itself with the textbook and:
S. Carroll: Lecture Notes on General Relativity (
http://pancake.uchicago.edu/~carroll/notes/)
John Baez: General Relativity Tutorial (
http://math.ucr.edu/home/baez/gr/gr.html)
G. 't Hooft: Introduction to general relativity (http://www.phys.uu.nl/~thooft/lectures/genrel.pdf )
These were what I personally thought to be the most interesting sources. There's lots more available but not all of it is suitable for selfstudy.
I also recommend Gerard 't Hooft's page "How to become a good theroretical physicist" (
http://www.phys.uu.nl/~thooft/theorist.html)
He was so kind to add some of my suggestions (and even my name!) to his site.
