On linux, use:
$ df -h
This prints it out in "human" readable form.

On Unix, I use:
$ df -Mk
This rearranges the columns so that it is more easily read.

As to database size, I would build a development DB and put it through the grind. Try to emulate real life scenarios, and real life dml, this will give you an estimate of what kind of disk space you will need.

Remember, disks are pretty cheap these days, and have huge storage capacities. Do you plan on using a RAID, SAN, or just use the internal drives that come with the server? There's many options, storage wise.
Good luck...

on Unix or Linux , you can use:

$df -k

It's hard to say. You may have to to work with the developer and data owner to set the plan up.
