I currently have a Linksys e4200 v1 wireless router that I have flashed to dd-wrt to run my vpn client on. This allows me to connect my Apple TV wirelessly to the VPN network and stream MLB.TV for my local team (otherwise I am blacked out due to location). That said, I would like to place a switch (Linksys SE2500) between my modem and the router so that I may connect my pc directly to the switch and then be able to easily turn the VPN access on and off on the PC only to in order to increase my speed. From what I've read, this should be relatively easy.

Now to my question. My wireless printer connects to the router. I assume that my other wireless devices (IPAD, phones, laptops, etc) that can currently communicate to the printer through AirPlay will not have any problems connecting in this new scenario. However, will my PC that will be running off the switch, be able to communicate with the printer directly or do I need to change some configurations on the wireless router? If so, can someone explain how I will go about configuring this setup?
 
it depends on what you care calling a modem. If their truly is a modem then it likely will not work. Not necessarily for technical reason but more because your ISP will only allow you to have a single real ip address. If the modem is actually a router then you can place the pc where you propose. In this case (well in both if the ISP give you a second ip) your problem is with the NAT and you will need to use the same port mapping solution you would to allow a internet connected machine to talk to your inside devices.

DD-WRT has the ability to run multiple vlans. You may just want to assign a port on the router to a different vlan if that is your intention. Also if you work at it you can define which traffic goes into the vpn and which traffic goes directly. You do not have to send all traffic though the vpn if you do not want to. you will have to manually put in list of ip addresses to send though the VPN though to make it work that way.
