Choose Social Club from the Start menu, then News I think, this gives you the option to hit Y which syncs your stats with the Social Club website.

Getting Platinum (or 100%GS) you have to literally do everything in the game including 100% completion (which oddly isn't 100% for real but...ok) Yeah, getting 100% is not a big deal because you don't need to do everything to get it.
Im gonna be pissed if i go through everything and it not show up on the social page.
