Service Desk Plus Customization Questions

Hey All

Am testing out SDP at the moment and showed the rest of the IT team yesterday and they have bought up some questions and need to know whether some of these changes can be done.

Can the end user portal layout be changed (ie change the way everything looks, increase the 'new issue' button and even rename that button, move the button to a different location)
For the job priorities, when on the request page look at all the jobs can the whole line be color coded with the priority color instead of just he priority column
Is there away for pop up reminders to happen when a SLA is nearly expiring, a job has been updated but the end user etc – Do not just want email notifications
