Install firewall clients in workstations you want allow internet access, join ISA to AD if you have one, create an AD group with all the users you want internet access and create an access rule with that AD group in USERS tab.
Second approach if you don't want to install firewall clients. Assign static ips to those users needing internet access, create a computer set with that IP range, place that computer set in FROM tab of an access rule and set the All Users in Users tab.
Actually, there are other steps involved. You should read/understand how to create/manage access rules.
