Yes, indeed, there is an easier way: Check the registers.
From what I remember, here's how it goes:

mouse:	btst	#6,$bfe001	;0 = lbutton up, 1 = lbutton down
	beq.s	out
	btst	#10,$dff016	;0 = rbutton up, 1 = rbutton down
	bne.s	mouse
out:	...

This will repeat the loop until either the l- or r-button is hit.

Ok, I have a question for the net: How do you read the middle button on 
a mouse? (i.e. optical)

Hope this helps. (And if the addr's are wrong, I am sure the net will correct
me, but I am pretty certain about the #'s I gave)
