1) Use construction lines via 'Draw'->'Con. Lines' in menus:

  a) Draw a horizontal/vertical construction line 
  b) Draw a parallel construction line - enter the distance in the entry
     box, click on the reference construction line, then click which
     side of that construction you want the parallel line to be located.
  c) Repeat as needed

2) Not sure what you want here - is this in regards to the creation
   of lines?

3) You can set the units via a dialog brought up by 'Edit'->'Preferences'
   menu selection. All coordinates in the drawing are now taken to be
   in the new unit, and values entered are also values in the new unit.

Do the answers above provide any clarification?
