Thomas Thorpe registered the book of Shakespeare's Sonnets (he got a licence to print the book) in 1609. The book was printed by George Eld, then sold through two booksellers William Aspley and John Wright.
In the first edition of the sonnets there is a very strange dedication signed T. T. (probably Thomas Thorpe again) which suggests that the sonnets were sourced from a Mr. W. H. (never identified).
Some critics have suggested that since the sonnets don't have Shakespeare's own name on the dedication, they may have been published without his permission.
But there is really no evidence for this. Perhaps Shakespeare just didn't think his sonnets were that important, and couldn't be bothered.

The volume Shakespeare's Sonnets [1609] contains 154 sonnets, so the usual answer to this question is 154. There are a few 'sonnets' embedded in the plays (particularly in Romeo and Juliet); but people don't normally include these among Shakespeare's Sonnets (for a number of reasons).
