Rendezvous isn't only matching orbits - you need to be at the some position as the target object. Matching orbits with the target when you're 1000 km behind it doesn't help.See above, TIG T1 is calculated only when EL != 0 - otherwise it is free.
... you are aware that
a) any rendezvous is a matching of orbits?
b) you only have spec 34 to calculate a hohmann maneuver?
Mission Control can calculate the required DV for a Hohmann transfer and provide it to the crew (this is how the NC1/NC2/NC3 burns are done, although they aren't Hohmann transfers).
