Re starting off - it's not too hard. Push in the accelerator, feel the vibration from the engine rise, push it in a bit more, when people across the street turn to look at you, then that's enough
Let go the clutch slowly, very very slowly. Yes, more slowly than that. Even more slowly.
Soon, doesn't matter if it takes 5 minutes, you'll come to a point where the car judders a little bit and takes up a little bit of the slack in the brakes. That's called the 'biting point'.
Let out the clutch a tiny, tiny, very tiny bit more, and you should start moving very slowly. Press in the accelerator a tiny bit, a tiny tiny bit more, and you will move a little faster.
You can play here with either pushing in or letting out the accelerator a tiny bit and feeling the change in the engine vibration and road speed, or doing exactly the same thing with the clutch.
It's an absolutely vital thing to learn, the two different ways of controlling your speed at low speeds, and the different effects they have.
Rev counters are useful when you are learning, so that you can learn what the noises and seat vibrations mean in terms of revs, but after that, when you're driving, you're too busy to look at it. So you do need to learn how to know what the revs are without looking at the counter.
I can do it and I'm deaf as a post
All cars have a slightly different biting point, so a very useful game is, when you first get in the car, slowly come up to the biting point then back off a few time, so that you get a feel for where it is. You can spend 10 minutes doing this, staying in the same spot, and it'll really help with your starts.
As you get more experienced, you can come up to slightly before the biting point quickly then slow right down for these last few millimeters. Nobody goes through it quickly, even experienced drivers - that's how you stall.
Hope that's been of some help.
