For 95AUD you did all right I think. They all look rough when you first get them but at least someone else has made the "keep the patina or not" decision for you so you can feel free to do what you want.

If the hub is original you have a bike that would be worth a bit of investment in to make it run beautifully. I don't know if you can get alloy rims for roller brakes or not, however there are replacement pads that will help braking quite a bit at a much lower investment.

Go read about your bike and its brethern on Sheldon Brown and Headbadge....and enjoy it!

ps. post more detailed pictures....close ups of all of the various bits etc. Its quite helpful and gives those of us in the cold northern climes something to look at....
