I barely know what I am doing (I am still learning) but at first was a tad overwhelmed but the guide coh3n has is amazing if you just take the time to sit through it (

It won't teach you everything but it will teach you what you need to know, I used this in conjunction with about 4 public scripts to learn the basics.
The way to find a script that will help you is to first find what you want to make then you look for similar needs in scripts ex: If you need to walk in your script, look at another script that requires walking. (Change things in theirs to figure your script out)
Also don't be afraid to ask, Luff/Flight/Risk and others helped me when I got stuck there are many people here who are willing to help just got to ask :)
Just use the resources we already have at our disposal before getting more.
Build yourself off others, if we all started from the bottom and went up we would never improve as a community but that is what I love about this community it is about growth.
hmm, I think I went off topic there haha
