As the title states I am looking for a compiled list of Campaign 1 and 2 original items created by the DM Legend himself. The reason I ask is because I am running a campaign in Exandria that takes place between campaign 1 and 2.

I often work 12hr shifts so I don't have the time to go through the videos writing info down or combing through the wikis, so if there is anyone out there willing to lend me a hand then I would greatly appreciate it. :) 

Also I know about the switch you can toggle during character creation for Critical Role content, I need to have a list and have the item details so I can plan accordingly in case my players try to search for them or if I want to give any as rewards.

Here ya go. Be warned though, many of them lack a statblock and only contain a vague description of what they do.

I think the only Exandrian items already in DDB are the firearms listed in the gunslinger description.

You can search for homebrew content that Matthew Mercer has made public on D&D Beyond, however the list is very short.

 Is there a filter or something, or are you just refering to the character sheet?

 Filtering by his username in a section will bring up his published creations. :) Here's a link for magic items.

Hmm.... I know for a fact that I saw a 5e (bore the 5e logo and the Critical Role logo, but I don't think it had the D&D logo) book at Barnes and Noble that was done by Matt Mercer and another person that goes over the campaign world. I didn't read it so I'm unsure what all it covers and I assume it from the first campaign of Vox Machina instead of the Mighty Nein. I'm planning on picking it up later and will probably edit this post when I do to go over the general things that the book covers from its table of contents page.

After a quick google search it looks like it might have been named the "Tal'Dorei Campaign Setting" but I'm already planning to go back to that same Barnes and Noble and confirm more of what I already saw.

That is a CR source book created by Mercer and published by Green Ronin, not WotC. I doubt we will see that in here any time soon as this site is an Official D&D tool set (meaning WotC, not RPG in general). However, we all hope to see 3rd party stuff in here someday, but it is all about licensing  and contracts. Right now, WotC holds this because without WotC licenses, DDB is kinda done for.

The only things you will find here are a few homebrew things and one official class. Interesting to note is we will get Acquisitions Inc though, but that is a joint venture between Penny Arcade and WotC. CR is a home game that went viral (that DDB sponsors).

Edit: Acquisitions Inc is published by WotC.

Okay, so I stopped by the Barnes and Noble and sought out the book (it was still on the shelf) and took some pictures of it's covers so you can hopefully see if its the kind of thing you were wanting. I have not watched any of the Vox Machina season of Critical Role, so I wouldn't know how much of it matches that season and even if I had, I couldn't transcribe the entire book here.

On the front cover you can see that its definitely Critical Role. So this would be the cover you'd look for.

Here is the spine. You can see that its 5e and I think the GRR 3602 is the module number that I've seen on other D&D products.

Here you can see the ISBN which can help with looking up the book as well as logos of other groups involved in it.

Here is a look at the Table of Contents for you to see if it has stuff you are looking for. I won't go deeper into the book than this.

"The Vestiges of Divergence" was a list of more than 15 items. I'm not sure how many were created for their campaign. Hopefully this helps and if anyone knows if Critical Role has made a book for their current campaign of the Might Nein then let me know. I'd be interested in purchasing that book as well.

That's a great book, by the way. I backed the Kickstarter and I browse the PDF all the time for ideas and to dig into Exandrian lore.

That book covers the continent explored during the first campaign. As far as I know, there is not a book (yet) for the continent in the second campaign. The book was published by Green Ronin, you can get a PDF version from their store.
