1, the car going straight on has to give way to traffic from left and
right, this includes traffic turning right opposite. (I have to confess I can't find this in the highway code, but I have always regarded traffic turning right in this scenario is to be treated as if they are on the main road)
2, right of way is for the car turning right.
Highway Code 160-166: Roundabouts
161: When reaching the roundabout you should
give priority to traffic approaching from your right, unless directed otherwise by signs, road markings or traffic lights

3, the car which enters the roundabout first has right of way.
4, as above.
5, the lane positioning is quite correct, as per the 1st diagram in the above link, however, rule 162 states:
162: Signals and position, unless signs or markings indicate otherwise.
When taking the first exit
signal left and approach in the left-hand lane
keep to the left on the roundabout and continue signalling left to leave.
When taking any intermediate exit
select the appropriate lane on approach to and on the roundabout, signalling as necessary
stay in this lane until you need to alter course to exit the roundabout
signal left after you have passed the exit before the one you want.
When taking the last exit or going full circle
signal right and approach in the right-hand lane
keep to the right on the roundabout until you need to change lanes to exit the roundabout
signal left after you have passed the exit before the one you want.
When there are more than three lanes at the entrance to a roundabout, use the most appropriate lane on approach and through it.

When on the road I guess in a lot of cases you have to use your judgement and common sense, I used to do a lot of cycling and the best tool I had (and still have)for awkward situations was eye contact, if I did not have this with a driver crossing my path then I was extremely wary.
On the road (esp roundabouts) you will always get your chancers and the plain clueless, just as long as you are aware of whats going on and make others aware of what you intend to do, you should be fine.
ps, apologies for offhanded reply earlier in this thread.
