SharePoint 2010 Installation and setup

Hi all,

Has anyone succesfully managed to setup correct a Sharepoint 2010 system into Avamar. I have been following the manual which is frankly useless when it comes down to understanding what should be 'front end' or 'back end' during the installation choices and I am also getting some strange errors during install.

It is also not very helpful when it comes to understanding what services should be running such as VSS and under what user accounts.

I have the following 'Dev' sharepoint environment

1 x Web server that users connect to.

3 x Sharepoint backend services servers

2 x SQL servers hosting the databases.

Install questions:

Should I install and then register the Avamar client to a grid BEFORE installing the Sharepoint plugin?

Which of the above should be a 'front end' install and which should be a 'back end' install

Should I install the 'front end' first or does the order not matter

Other questions:

Wht depedant services are required to be running either pre or post install

What user accounts should these services be running under?

Is the best way to test success to ensure I can browse the sharepoint 'tree' as part of the data-set defination?

If this is 'in the manual' whereabouts should I be looking?

Thanks for the help.
