First I would suggest taking the MSF course.. reason you wont know how to corner without it.. or atleast wouldtn know the right way to corner and take turns.
Once you get that, then you can start riding. The reason I am saying this because the MSF course teaches survival skills that is not easy to learn otherwise.
If you do get on to the bike make sure you take is slow, that means ridinging within your limits, that means no speeding, keeping to the posted yellow signs for a turn and taking it carefully. The biggest mistake a newbie has with is with turns. THey cant turn. Learn how to turn, if your dad knows how to ride and has been riding for years then have him teach you the basics. If not I would suggest to lay off until you are done with the MSF. The thing is when you turn you need to turn your head to the direction of the turn and look thru the turn, lots of newbies dont know how to do it. Counterbalencing is also required to take turns.
When you start riding, please wear leathers.. that means a leather or cordory jacket and jeans. Doesnt matter how hot it is, its better than having your skin on the hot asphalt. Also drink a lot of fluids, you will never know what hit you when you are dehydrated.
As for "waving" I hardly wave, out here we use the head nod or the flash of the headlights. Its true that there is a sort of camarade between riders but if your a squid they wont respect you. Harley riders dont wave back so dont bother (well 99% dont wave back - they are too concerned on holding on to their rattling bikes).
And what ever you do.. please use your brains..
Ride Safe, Ride Smart....
