I have Questions

I'm starting this blind and I have lots of questions. 

I don't know how to do the transitions.   I don't know what I need to make transitions or how to set them up. 

Silly as it sounds, I don't know what to wear.   I guess that people bike and run in their swim suits.   In videos, it appears that many people compete is something like a singlet but I can't tell if that is also the swim suit.

Now that I am swimming, I don't know what to do about my hair.  With an hour plus swim 4 days a week and taking 2 or 3 showers a day after workouts, my hair feels like it is trying to suck all of the moisture out of my fingers when I touch it. 

I don't know how to manage food and fluid during the event.  For the sprint triathlon August 4th, I'm not too concerned because I feel like I can handle the bike and run without needing food or fluid on the actual bike and run but for longer events, I'm a little at a loss.  I just bought a new camel back to help me when I bike but I'm not sure if people are allowed to use things like this during events.

I have some equipment questions to figure out along the way.  Most of these involve things for the bike and clothing to wear.  

I'm still figuring out the training schedule.   When I sit down and work out a schedule, it is awfully hard to get it all in.   Right now I am really working on the swim because right now, I still cant swim continuously for 800m (at least not free style.)   The swim is getting much better but I have lost a lot of my endurance running in sacrificing running time and distance to swim more.   For now I am in no danger of being unable to do the bike and run distance BUT as I gear up for longer races, I have a lot of work to do.

That is just the beginning.  As I go along, I am finding more and more questions.  

Speaking of which, as I have been saying all along, I am open to questions if you have some AND of course I would love it if you could offer some of the answers!

Have a great evening!
