Hello and welcome,
Congratulations you have realized there is more to RC than boring holes in the sky. Be careful as pattern can be very addicting.
Also, check the contest calender July 12 there is a contest in Hudson, NH that would be a great opportunity to try your hand and meet some other pilots in the area. You can learn more in one contest than weeks of flying on your own.
Good luck and keep trying.
I 100% agree with everything that Anthony-RCU said - especially the statements above. You might be amazed at how friendly and helpful the pattern guys (like most modellers) are. Even at a competition. Look, Listen, Learn and practice paractice practice.
With the Dolphin you will find that the dihedral tends to make the plane stable and want to fly upright. but the flex in the elevators will certainly contribute to the roll out.
If you can - get someone from your club (it doersn't need to be a current competitor - most clubs have experienced guys) to help you when you practice - smooth, even gentle movements are what you should be aiming for right now - large diameter and ROUND circles and straight lines for each move. As you progress with your experience, you will find that accuracy will come automatically.
