There's a lot of contradictory information about Unix server partitioning out on the internet, so I need some advice on how to proceed.

So far, on the servers I in our test environment I didn't really care about partitioning and I configured a single monolithic / plus a swap partition. This partitioning scheme doesn't seem like a good idea for our production servers. I have found a good starting point here, but it seems very vague on the details.

Basically I have a server on which I will be running a basic LAMP stack (Apache, PHP, and MySQL). It will have to handle file uploads (up to 2GB). The system has a 2TB RAID 1 array.

I plan to set :

/         100GB 
/var     1000GB (apache files and mysql files will be here), 
/tmp      800GB (handles the php tmp file)
/home      96GB
swap        4GB

Does this sound sane, or am I over-complicating things?
