Request for information

I have been asked to provide to my manager a document outlining what is
required to create failover clusters for our application servers using
Windows 2008.
In particular:
A web-server running multiple sites under IIS using dotnet (32 bit
currently)
A mail server
An SQL server
The purpose would be to provide fail-over redundancy to our systems so that
if the server in question failed, it's partner would take over. In our wish
list, this would all happen automatically and applications would just work.
Of course web DNS is done by IP, so whether that is actually possible or not
I do not know...
Can you point me to documents that outline the basics of the type of
hardware needed.
For example, I know that under win 2008 we require identical servers using
hardware components that are Certified for Windows server 2008. I know that
we need some type of SAN device. Beyond that I don't know how it all goes
together.
For example, since we are looking at 3 clusters of 2 nodes each, can they
share a SAN device between the 3 clusters (if it meets certain criteria...
and what would that be?) Is there a performance hit if the SAN uses Gigabit
Eth. or ISCSI (never used ISCSI not familiar with it).
I am not even sure what questions to ask at this point... so if there are
documents that explain this... enought that I can outline what type of
hardware (not brands but capabilities) I'd appreciate it.
