There are many great clinic videos on youtube if you know what to search for, look up feldberg on youtube he has good clinics especially putting. The sooner you develop proper form and technique the better you will become.
I second the high speed driver advice, avoid them. The fastest driver you should be throwing is a speed 9 until you can throw over 400ft.
Find a versatile mold, and stick with it, I threw Innova, then Lat64, Then MVP, then Legacy etc.. I finally stuck with MVP but the latest released driver is not going to make you better. Developing muscle memory with the flight of any given mold that you like over time will make you more consistent. Every major brand makes good discs, find what you like and stick with it and dont change. Teebird, Volt, Rival, Saint, whatever.
See if you can find local doubles leagues every week, its a fun way to have a little competition and test your skills, meet new people and playing with others that are more skilled will help you get better.
Most of all have fun, dont get too serious about the game. Enjoy the challenge and process, before you know it you will be looking back and will want to have good memories of having fun.
