WELCOME TO THE AWS WELDING FORUM!
That is going to depend. What are you wanting to do? TPI with your own business? Work under someone else? Company QC?
If going into business for yourself you really have a long way to go. If working for someone else it all depends upon how much additional tooling you will need for your sector of the industry, weld measuring devices, computer, more code books, etc.
As far as study goes, there are other threads here with the same questions and information, but, WIT, it workbook and practice exam book, Your chosen code book, and the Part B which is downloadable from this website under certifications. From the forum you have to go to the 'AWS Website' first. Then to certifications and just start going through everything. You'll find it.
Read everything at least once but concentrate on those books and you will do fine.
