Wow... the man himself Dr Pete!! Thanks for the info. Much appreciated. I've decided to go with both Moz Pro AND Screaming Frog.

Mo Info. Mo Power. Mo Money

Using the words of a great SEOer... Annielytics:

"Search engines use the H1 tag to interpret what a page is about, much the same way readers of a magazine use article titles to get an idea of what an article is about. When pages are missing H1 tags, it’s harder for both visitors and search engines to decipher what the page is about. The H1 tag should contain a judicious use of the keyword(s) you’re targeting the page for. Be careful to make the language natural and not keyword stuffed. If you have to decide between user experience and SEO, go with user experience."

I would just concentrate on using the H1 tag to add value to the users experience. I guess they will already know that they are on your website, so no need to remind them of this in the H1. As Annie mentions above, use it like you would if it was an article in a magazine. You wouldn't repeat the magazine name within an article title already in the magazine.

also, the 'beginners guide' link that Matt Roney has shared is a great resource!!

Hope that helps!
