Creating stand-alone learning stations

[ZephyrQ]

I'm a high school special education teacher who has been given 
permission to test Linux on a few laptops to use as workstations.

I've installed Edubuntu on 3, and would like some direction concerning 
creating a 'skeleton' desktop so every new user created has the same 
(limited) options.

These stations will be used as both learning (I am in special need of 
reading software) tools and incentive (my classroom specializes in 
'behavorial needs' students.

Can anyone direct me the to the right sites/documentation?

Thank you.
