I've only blocked once. It's not actually vital. I mean, it can be helpful and has it's place etc, but I personally don't consider it to be necessary.
I hate weaving in ends. I am not very good at it. But I do it. I get better. I take deep breaths.
Depending on how long that "tail" is that's left over from the cast on, I either wind it in itself (so I don't accidnetally use it for knitting) or hang it on a bobbin. I found some at a yard sale. I would have never bought one new, but now that I have some I'd buy more.

When I'm done I weave that end in too, unless it's super long, then I weave the part closest to the knitting in and clip the rest.
Your library should have at least some books

I hope you have some nice librarians to help you find them.
Of if your librarians are mean like mine you ask here
