So, it looks like you got the information you needed, but here in a condensed version for you. 1.) Learn the basics before songs. I.E-String names, and basic chord locations. (A,E,C,G,F,D) learn to pick different styles. like (D,D,DUD).
2.) Looking at the strings in totally normal, your brain knows you don't have the muscle memory just yet. Just keep at it.
3.) Acoustic are good to learn on because they require more pressing force than an electric, it's all preference. Though @docwarren is right, electric steer towards power chords way more than acoustic.
4.) In regards to your question, Youtube is always a good place to start, but you need to know what you are searching, or if you are wiling to pay a small subscription. Yousician on Google Play and I believe Apple Store is an amazing app to learn.
5.) Practice Practice practice and you'll be the next Joe Satriani ( https://www.youtube.com/watch?v=Yo6LXD7uzn4 )
I used to play often but don't as much anymore. Make sure to just play it a couple hours a day. Remember, you can only improve.
