Yeah complete means balance.
Thanks for the solutions guys really appreciate it, just a couple things:
1C you put the amount in the creditors control column. Do you reckon there's any possibility it may have been 'sundries'? I put creditors control too but some people are saying sundries which is a fair point.
2C: I said assets decrease by 450 (1), creditors control decreases liabilities by 485 (2) and GST clearing increases liabilities by 45, leading to an overall decrease in liabilities by 440 (3) - however I didn't mention no effect on owners equity, would I lose a mark?
Looks like atleast 6 marks off for me -_- Well there goes any hope I had of getting into my desired course! 
Thanks again!
Hm.... Sundries would be correct assuming that Lyall's Imports trades in stock that does not include Leather Chairs.
The information doesn't provide us with any indication of what Lyall's actually sells. To me, it seems inconclusive.
I can see the argument for Sundries - the may just be buying the chairs for their office etc.
However, I don't think we've been given enough information to draw that conclusion. I hate it when they don't give us enough information

2c would depend on how the answer booklet template was set up. Usually, you always mention the effect on OE. This would be a requirement if they had given you the three row template (Increase/Decrease/No Effect table). It's usually always better to err on the side of caution and include it. I'm not sure how they'll assess it.
P.S. if you only lost 6 marks, that's still pretty damn good mate!
