To answer your question ( IE "How do I turn?" )

You are now going to learn to do an Aileron Turn.

(Historical note: THIS, above anything else is what put the Wright Brothers way ahead of their competition)

First, you bank the wings with the ailerons, let's say to the right (don't worry about how much just yet).

As you know, this won't cause the plane to turn, but now (See picture) gravity wants to make the plane slide down and to the right (Arrow A)

Now, (Note: Some planes require that you continue to hold the bank with the ailerons, and some do not) while maintaining the bank, apply UP elevator.

As you know, "UP" is a relative term (In other words, UP means DOWN when you're inverted) So since your wings are banked, "UP" is in the direction of Arrow "B".

The combination of the two forces result int the plane turning in the direction of Arrow "C"

Now, as far as "How Much do you bank?" let me ask you this: How much do you turn the steering wheel of your car to make a turn? It;s impossible to say because all turns are different.

The more you bank, the more up elevator you'll need to keep the nose level. But you MUST remember two things:

1 - To tighten a turn, you must use BOTH controls! By just adding more aileron, you will only roll the plane (As you found out). Once the plane has reached a 90 degree bank, continuing to bank will make "UP" become "DOWN". So the tightest turn you can make would be to roll the plane 90 degrees, and apply full UP elevator.

2 - If you ever get in trouble - LEVEL THE WINGS before you do anything else! All too often a rookie goes for his first "Walk of Shame" because he banked too far (Semi-inverting the plane) and then panicked and pulled "UP" (See note about "UP" meaning "DOWN")
