Did I open the ISA firewall door too wide?

We're running Windows 2003 SBS R1 with ISA 2004. Our network has SSID
and password controlled wireless access.
I have two questions:
1) Did I open the ISA firewall door too wide?
2) Is there a better (no additional cost) solution?
Previously all our clients had to have a proxy server configured in
Internet Explorer LAN Settings in order to access the Internet. We
changed a setting somewhere (I cannot find my notes) so that guest
laptops who had the SSID/password on their wireless could access the
internet without being able to access any other internal resources.
Somehow in the last week that got unconfigured.
To restore access I went into ISA Server Management and selected the
Firewall Policy for our server. I then went to the SBS Internet Access
Rule and selected its properties. The Users tab had SBS Internet
Users. I added All Users. Now the guest laptops, whose owners do not
have accounts on our domain, are able to access the Internet through
our wireless access points but don't seem to be able to access
anything else on the server.
Did I do right? (I'm a volunteer administrator of my church network
and I really do not know much about either SBS or ISA. I'm learning,
but ...)
