Welcome to the crowd Eric!
The first thing I recommend is that you should invest in a guitar tuner. Probably at this point anything that has a microphone built in so that you can tune both an acoustic and an electric. If you have one already, bust it out. You're going to always want your guitar fairly well tuned when you practice because a big part of practicing will be to train your ears.
The second thing I recommend is that you should invest in a metronome (or download a free one on a phone/PC/laptop) and do these exercises with it on. Always. For months. If you have one already, bust it out. In the first video, very often you'd play a set of notes (for example 4) and then there would be a pause when you'd move to a new string. Then you'd play again. etc. You're goal just starting out would be to play at a slow, but constant and clear, pace. Not rushed, then pause, then rushed, then paused. That's not what you want. Do it like Pebber instructs in his videos. If his tempo is too fast to start out, then go slower. Maybe 40 bpm is a good setting.
I don't think you should worry about the scratching sound too much at this point. It scratches because your pick is tilted at an angle and when it scrapes over the wound strings you can hear the scratch. Tilting slightly less will limit the scratch and also change the tone of the attack. If you can try to ignore that until you spend a lot of time with the metronome, I think the tone of your picking will gradually improve automatically.
Bust out that metronome.
Oh, and we all suck. That's why we're here. So don't be nervous when you're posting videos :) Just keep working and you'll see results in time.
Bust out that metronome.
Finally, from the last year that I've been lurking/posting this forum, the general (and very wise) consensus is to place every bit of instruction that Pebber and Ursin offer you as infinitely more important than everyone else's on these forums. And when you eventually get to Sarod picking, add Frakh to that list.
Good luck!
