Namdac is right, start collecting standards.
As you're based in the US, focus on the ASME series of standards first, unless you're specifically detailing for an ISO (International Standards Organization) or JIT (Japanese Industrial Standards) market, in which case start there.
ASME Y14.5M-1994 covers notes, tolerancing, GD&T, dimensional units, and much more...it's a lot of reading and thinking, but it's an essential resource.
ASME Y14.43-2003 Dimensions & Tolerances for Gages & Fixtures
ASME B46.1-2002 - Surface Texture
ISO 286-1 & -2 -1988 - ISO Limits & Fits (Parts 1 & 2)

One last note; ASME standards are fairly robust and encompass many subsets on a given topic in single documents; ISO breaks down a main topic into numerous related fields, and charges you for each sub-section you get. ASME gets far more bang for the buck, and much of the world (corporate, not political) is starting to step back from ISO and adopt ASME as it is based in a practical rather than a theoretical system as ISO is.
