I am sure there are more experienced people here that would be better at helping.
I have a very similar 3D printer, so I can go through what I did to get it working.

Those settings look ok to me, but it seems to depend a little on the exact plastic used. When it comes to buying more plastic, try and get something that is repeatable (ie. the RS stuff).
The bed needs to be very level for it to stick well. I spent about half an hour trying to get mine level. If you are having problems with it being level, you can use a raft, which will make a layer of plastic that should be a bit more level.
I use some extra wide masking tape on the base then spray it with hair spray to help it stick.
