comment Textbook on the Geometry of Special Relativity
I really enjoyed Tensor Geometry by Dodson & Poston; by rights it will give you a healthy foundation for General Relativity but treats the Special theory at the outset. books.google.co.uk/books/about/…

comment Coleman-Mandula theorem in mathematical language
I find that this paper is particularly accessible and constitutes a nice derivation of the individual elements of the proof. ippp.dur.ac.uk/~busbridge/files/documents/CMtheorem.pdf

comment Difference between $SU(2)$ and $SU(2)$ gauge transformations?
The word gauge here relates to the redundant degrees of freedom in a Lagrangian (specifically). The transformations between all these possible gauges are called gauge transformations and the will form a Lie group—referred to as the symmetry group or the gauge group of the theory. Is this what you're getting at?
