Just had a front suspension bush replaced on my 20. TDI PD at the mot.....Should I consider get the car wheels tracked again?

I guess that depends how worn your tyres already are: if they're going to be changed soon, then have a proper four wheel alignment done when you change them. If they're new, then it's a good investment in getting the best life from them. No matter how careful the mechanics were, something will have moved a bit....

Hadu a noise in front going slow over bumps? Did ur new bushes make any difference?

I had no noise when going over speed bumps, the bush had to be replaced to pass the MOT. I have noticed a type of whoosh noise over speed bumps the same as a golf, I said to my wife 'It sounds just like a Golf'

Ye that noise is just ur shocks priming it's normal
