Hi Johnny - Welcome to Pherotalk. 
Your choice of pheros is pretty-much spot-on for someone starting out, they give a good mix of sexuality and social attributes that are good for boosting your confidence and breaking the ice with people. I would suggest you stay away from the Putatives and MXs to begin with though - these are experemental products that are not sold with a warranty and a bit of time with the instants first will help you learn how to use and evaluate pheros/hits/responses properly - then your reports will be all the more valuable.
Shyness - well, you just need to work on that as pheros won’t be the whole story but as you do, things will fall into place nicely. There is plenty to help you here too and links to where you can find more info still.
You are also asking about the alpha thing - well, A314 is the product for that and I’d say the oil is by far the better product for long term change/acceptance. Long lasting and far more subtle in its effect. Sprays are more present and good in more social/dating situations but I would still see them as an emergency top-up to the oil or the -b version as an effective try-out.
All the basic info on choosing and using pheros is in here:
