Having trouble with the title and with h1 on homepage

Hello all,
This is the first site I’ve done, using step by step YouTube.
I think that I’ve done a mess with the homepage, and especially title and description.
Looking at the source page of homepage, I see that the title and description are tied together:
1. The word “Home”

<meta property=”og:title” content=”Home | Spy shop | Bugs listening devices | Spy transmitters | Spyshopro” />

The “Home” is my first problem. Even if I delete all the other words, “home” remains. Usually, on most sites I know, the title is not “home”, so I wish to get rid of it. If it is possible, I wish to get rid of it.
2. The title and description are messed up:

<meta property=”og:description” content=”SPYSHOPRO SPY STORE SPYING DEVICES | PROGRAMMABLE BUGS | RECEIVERS OUR SHOP CONTACT STABILIZED BUGS Powerful spying and bugging transmitters working on the ISM band, 433MHz and 418MHz….

How these appeared (the bold ones), and how to fix this mess?
3. Last one (meantime…): Bing web master tools shows 2 warnings:

The <h1> tag is missing.
The description is missing in the head section of the page.

Again, I need assistance to fix it, as I would say that I am an ignorant in this field.
I know that for several bucks a freelancer may fix it, but my goal is mostly to learn and not getting a “ready made” site.
Thanks in advance!
