I have the following;

1.      A Cisco Catalyst 3750 which is acting as my firewall from my ISP
2.      A Linksys Firewall(Wireless capable) connecting to one of the two ports on the Cisco  Acting as my Private network DHCP and Wireless access point
3.      A Netscreen 5GT connecting to the second port on the Cisco  Acting as DHCP and Wireless access point on my Guest port of my network

So the Cisco is getting a IP from my ISP and NAT it out to two ports internally One 10.20.XXX Private network and the other 20.30.X Guest network

What I would like to do (wanting the easiest to setup):

1.      VPN that will allow me to VPN from the outside world via my laptop to my home network
2.      VPN via my iPod Touch which is WiFi from anyones house who grants me access to their wireless network or hotspot
3.      From within my house be able to connect to my wireless network via a VPN connection with my iPod Touch

First off does these options sound remotely possible with what I currently have? And second of all is it going to take a week to configure.

The iPod Touch supports VPN configuration with the following options


Needs Server Name, Account, RSA SecurID (on or Off), Password, Secret, Send all traffic etc., Proxy,

Server, Account, RSA SecurID, Encryption Level

Server,  Account, Password, Use Certificate, Group name, Secret

From my understanding the 3750 does not support VPN configurations so you will need to pass the vpn traffic through the 3750 and configure the Linksys firewall for VPN access. If you have access list on your switch you will need to open the proper ports for the VPN. You will also need to forward via nat your vpn ports from the switch to the linksys firewall since NAT is handled at the switch. IPsec ports are UDP 500 and UDP 4500.
i have never setup a VPN with a linksys but I wouldnt imagine they would not be too difficult. Documentation for setup looks pretty straght forward. It looks like they support IPsec VPNs so that is the route I would recommend.
