As an instructor I would reccomend doing the Adventure Dives first, with PPB as one of them. The best thing you can do for bouyancy is dive, dive, and dive some more. But youll get the most out of AOW right now, than after 50 dives when youve done it all.
And yes, tank bouyancy is covered in OW class. PADI tells you to float at eye level with an empty BC for proper weighting, then add a few pounds to take into acct an empty tank.
