replacing bushings

[gbsurf]

hello there.... thanks for reading i have a 94 3l auto kzn130 and it has one or two knocks and rattles. i took it too a mechanic and he thinks on of the probs is the worn bushes on the wishbones on both front wheels.. he told me that both wishbones would need to be replaced !! im no mechanic but surley can i not buy just the bushes from milners and just replace them?? in fact could i not do it my self ? how hard is it??? i think milners part no is 005316
is that the right one? has any body don this?......also one cv boot has split and is leeking grease front drivers side wheel... i wonder what i need to replace that?.....ok thank again for reading any advice at all would be great
ta for now
