At this stage of your golfing career it is easy to get confused, so you'll have to listen politely and decide what fits you and what doesn't. Tell them you are taking lessons from a golf professional and that may be all the input you can handle for now. Its easy for a new golfer to try and digest to many suggestions, stick with the professional. Most new players are a little apprehensive about playing with people whom they think play well. If you learn to get yourself around the course quickly and are aware of the rules to some degree they won't mind playing with you regardless of the score.
Slow play seems to the one thing that gets everyone on the course upset.
You can avoid this misery by being aware of what's going on and be ready to play when its your turn. Don't worry about how well the other people are playing, just enjoy yourself and try and learn something about managing your way around the course every time you play. It will get easier each time out. Stick to your practice routine but remember you have to practice but have to play also. The playing is just as important to your improvement.
