As JF has said us mere males aren't so good at multitasking.

.. which is why the ladies are streets ahead of us mere males in a great many endeavours ... bless their little cottonsocks ...

Spacing: If NG put the Map range to 5nm; put the TK line // to the Rwy centre line. It's a picture and the Rwy QDM doesn't matter. To allow a slight square base leg and give room for some adjustment to the descent path before finals you need the rwy to be 1/2 way between the 1st & 2nd ring.(Does the classic have range 5nm or still 10nm as minimum?) When you've established this pick a ground feature ahead to keep on track. Be aware of tail or head winds on base leg and adjust accordingly.
If flown on the line a CDA visual circuit is preferable. Flying lowish level with drag and level flight is frowned upon.
