some of those panels are prob just about ready for the bin and some will prob do ok
i would prob keep an eye on ebay and see what you can find
other options would be prob worth you looking at buying a plastic welder and having a crack at it since you have a fair bit of work there so would be cost effective and good for practice for future bikes
for small stuff i have had some success with
http://www.plastex.com.au which is good for small ones and missing bits but for the amount that you have the money would prob be better spent on a welder , check ebay
bugger reread your post and pics
looks like just a nose piece , depending on how good your work is , it should be ok nice welding btw
what is important is when you put the bike back together that all the panels fit properly and all the brackets are in the right spot , if you have to force things to get the bolts to line up this puts pressure on the plastics and this is the reason that fairings crack and will crack along the previous breaks
