>>> 
>>> the space you want to end up in depends on what you will ultimately use your data for. If the purpose is to register EPI data for group-level analysis then 2mm is enough. If you want to do detailed anatomical analysis you may want to go to 1mm.

>>> I mostly recommend registering to the 2mm template (using the usual configuration file) and then resampling to the 1mm template with applywarp.
