It sounds like you have a fairly lengthy list of items to address there,
not least being on such an old version of TSM but also how you are
managing your storage.  In my opinion, you need someone to come and
visit you and assess your environment then come up with a plan of action
that will get you to where you need to be.  A local business partner
that knows what they are doing will be able to do that and give you a
good idea (and price) for the hardware you actually need rather than
some sales pitch.

You might be able to upgrade the existing 3584, adding new drives and
partitioning, depending on the support status.  I suspect you will need
at least a new server for TSM, and might want to select what you're
doing about platform choice etc while thinking about how to migrate
across.
