Skip the first 50 pages or so. The rest is golden.
That said, my advice would be to not get too caught up on the names and places and details — just let the story sort of wash over you. Many, many, many names are only said exactly once in The Silmarillion; if you try to remember them all, you'll go crazy. If you see a name 3+ times, that's when it's time to track them down on the family tree, probably.
I'd also recommend making sure you reference the map when a place keeps being mentioned. It's helpful to know the vague locations of Doriath, Nargothrond, Gondolin, etc.

The blog is a rough draft of what I'd hoped would some day be a completed work, so it's not everything I'd like it to be. But I do think people will find it helpful nonetheless.
They are all largely self contained, and it's much easier to go through in quasi-reverse order. Just use the Wikipedia synopsis to get up to speed on the chronologically preceding section first. (https://en.wikipedia.org/wiki/The_Silmarillion#Synopsis)
