The CompTIA's that you have are good, but adding a Microsoft and/or Cisco makes you more marketable. -Routing and remote access - Would guess you could get familiar with how to use it/set it up (RRAS). VPN's/Firewalls are good to know as well. -Troubleshooting Cisco Routers - Really depends on the position on how much you will have to deal with them. -VMware - Familiarity with Virtualization, using the products (ESXi, VMware Server, VMware Workstation). Also some management programs (Vcenter). Those are either paid (free trial), have a lesser free version (VMware Player), or are completely free. -XenServer is another Virtualization platform like the VMware products. As for learning them, I'd start with VMware Player or ESXi for free. Otherwise buy VMware Workstation. Learn/use them. Create VM's, learn to troubleshoot issues.
