rangerxp,
Unless you have a lathe and some machining skills you will need to have a smith thread your barrel and install the brake.Depending on the brake style some will need to be indexed.It is a realtively simple process if you have the right equipment and know how. Here is a couple pix of brakes I manufacture and install which need indexing.
I have seen benefit from pillar bedding a synthetic stock, but if you are planning on upgrading your stock in the future then I would recommend waiting.
FWIW,
