The requirements for GUI & ReST API aren't  actually that dramatic. It boils 
down to three things:

1) CCR. This is part of the base package but you need to migrate you config 
from server based to CCR which comes with the added benefit that your cluster 
config is now truly HA.
2) mmhealth/mmsysmonc. This comes with the base package as well.
3) mmperfmon. This comes with the pm-sensor packages that need to be 
distributed accross all nodes. And the pm-collector that sits on the GUI node 
(in large configuration you might want to have more than one collector).

So from a package point of view it is basically just the pm-sensor package that 
needs to be installed all accross your cluster.

It's possibly worth point out you don't actually *need* the mmhealth/mmperfmon 
stuff to make the GUI work if you just want the basic API functionality (for 
managing filesets/quotas etc) - although obviously the actual GUI won't look as 
attractive in that case.
