I'm trying to setup a VPN with a Linksys RV-042. I have 2 issues:
See diagram attached for details

1. Linksys RV-042 in router mode, can't connect a computer to it and get the internet
2. Cannot see any computers behind router 1
3. Trying to figure out the best way to configure this setup to work with client VPN's

What s the VPN between? the RV042, a client, a remote router? The client or other VPN router cannot use the same subnet as the RV042 (192.168.254.x).
The RV042 needs to be in gateway mode not router mode, and why is it in parallel with the BEFSX41? The BEFSX41 will block traffic from anything on it's Internet side. Could not the RV042 replace the BEFSX41?

More information would be helpful, but assuming you want the above physical connections the WAN Internet side of the two routers is fine, but you need to change the LAN sides  to something different like 192.168.253.x on the BEFSX41, and 192.168.252.x on the RV042. Then enable gateway mode on the RV042. This will allow both networks to work, and have Internet access, however they will not be able to access resources on each other LAN's.

Also you cannot configure the VPN access from the Internet. In order to do so the RV042 needs a public IP not a private IP like 192.168.x.x  which requires the modem be changed from NAT mode to Bridged mode. It also requires you to have an account with your ISP that supplies more than 1 public IP, or remove the BEFSX41.

In order to not screw anything up would I have to change the RV042 to the 192.168.61.1?

If only one public IP is available will the client VPN still work or will I need to use a Dynamic DNS service?

If you want to use a VPN you need to:
-put the modem in bridge mode, as per:
http://www.netopia.com/support/technotes/hardware/CQG_020.html
-put the RV042 in gateway mode, not router mode
-set the RV042's WAN/Internet interface to DHCP (unless you have a static IP)
-this will assign the public IP to the RV042
-then configure the RV042 and client for VPN access
-The BEFSX41 will then only work if you have multiple public IP's. A DDNS service does not help with this, but rather allows you connect to a domain name which tracks a changing dynamic IP.
