Just brought 05 Megane sport tourer 1.9 DCi privilege with Luxury pack

Few things need doing
1. 'Oil change soon' message appeared. Renault Dunfermline quoting £50. Sounds expensive ??. Could shop around ie kwik Fit but would they be able to reset the 'oil change' message
2. Dipped beam on drivers side out (bit annoying as was MOT'ed by selling garage last fortnight). Looked at instructions re changing bulb on this website - got bulb from halfords, took off wheelarch access panel - all I can see is a sealed unit with a yellow lightning symbol on it - no further covers to remove and doesn't look like pics on wbsite. Is it a Xenon unit ??. car does have headlight washers, but hadn't noticed the lights were particularly 'blue'. If so guess it's going to cost me couple of hundred ??
3. Passenger side fog light smashed - anyone now how easy to replace, bumper off or not ?
Cheers for any help
Tom
