Looks like a tidy car Mad,
Obviously the first point of order would be a MPFI/T5 conversion. However if you are not interested in doing those I would suggest the usual lower, tint, clear indicators
but a few smaller things you can do which when added together make an overall improvement are things like
EB T-Bar handle - MUCH better lookin than the EA
Footwell Lighting - looks classy at night
Change Dash Lights to Red - only colour that works
Colour code the door handles ( mirrors too if u like )
EA Falcon sticker
