Going to be purchasing some solid engine mounts aswell. Do i only need to buy one

? or is there more engine mounts ... any help appreciated...
Also, gearshift is sloppy ... 2nd is crunching sometimes , what do i need to bring the box upto speed and back to normal, i read about some sort of reconditioning kit / bush kit ... who and where do i get this from and at how much ??
Thanks again people..
1st week into owning golf and i have already spent £300 - 400 with another load of things to buy aswell... going to be good though once everything is done ...
