Hey Steve, MkIV gives sound advice on these things. I have installed a ball joint upgrade and saw/felt a huge improvement. I'm not sure what's up with rear shock mounts these days but look for 4 bolts in place with a spacer/crush collar between so the bolts don't collapse the brackets. Sounds like you've done your homework mate. You'll have a blast with it on the coastal roads. Those Avons are a good call too. Keep your eyes skinned for the "brown paper bags".
Congrats.
