We recently contracted with a second ISP for redundancy. I have been looking for instructions on how to set this up, but have not had much luck. I did find the following articles, but none of them actually show how to completely set it up:
How to Configure ISP Redundancy and Load Balancing This one comes close, but some important steps are missing
How to Setup a Palo Alto Networks Firewall with Dual ISPs and Automatic VPN Failover Again, comes close, but I don't need the VPN info
Can anyone provide better instructions for how to add a second ISP for redundancy?

I think you may follow the second DOC without VPN tunnel. It means, in the VR2, you have to define the static route pointing towards your ISP-2 IP address, instead of a tunnel interface.

We only have one internal subnet, do I have to create a second VR or can I just add a static route to our Comcast modem with a higher metric?

I would recommend you to have 2 separate VR, one for Primary ISP ( through PBF) and another will be for Secondary ISP ( through touting table).

I just accomplished this with the following DOC:
Dual ISP Branch Office Configuration
Works great with one VR! we used two different zones forthe two different external ISP's but that just means we had to double up or combine our rules. There were only a few anyway.
