Welcome to the addicting world of Etsy!
I definitely feel you on the overwhelmed aspect. I've been on Etsy a year and a half and I still can't keep up with everything I need to be doing.
First off, focus on your shop. Your items, descriptions, tags, PHOTOS, banner, etc. If your shop is amazing it's easy to get views and hearts that will eventually lead to sales.
Once your shop is in good order, then worry about everything else. Set up a Twitter and Facebook to help you promote your items. Then you can venture into teams and blogging.
That's my opinion anyway. Really focus on your shop first. Get a ton of items in your shop, create a banner, make your descriptions and tags amazing, have great photos. The rest is all secondary to that.
Good luck!! :)
