Well fokes I managed to change the front relectors without taking the bumper off, howver I did take the wheels off to make access a bit easier.
I also found that taking a few of the nuts off the washer bottle's made access alot easier as I could bend the washer bottle bracket back enought to get better access.
Still all good now looks so much better with teh clear reflectors.
Also just to clarifiy do I really have to take off the inner wheel arch linning to chnage the indicator Bulb
Thanks all for the advise
