[Homeroast] Pruning an indoor coffee plant

I have two 10+ year old coffee plants (one is about 4' tall and the 
other is slightly shorter (it had a hard life as a youngster) that 
seriously need pruning and I need some input.  I have researched this 
on the net and have not found conclusive answers to the following 

1.  Do I have Arabica or Robusta plants?  They were sold to me as 
babies and were labeled Arabica.  But they have multiple "trunks" 
like the pictures of Robusta that I have seen.

2.  How far back can I prune them?  Since they winter indoors in much 
reduced sunlight, they have thinned out near the center with more 
leaves at the tips and the trunks have gotten top heavy and are 
bending over.  I would like to cut them back severely and let them 
re-establish new trunks.

3.  WHEN should I prune them?  This question remains relatively 
unanswered per the net.  These are outdoor plants in the summer and 
they winter indoors.  Not sure if they ever become "dormant".

BTW, they both flower and produce cherries but they take so long to 
mature that they are still green by the time the plants move indoors 
for the winter.
