Just picked up my second mx5, an na8 this time, that I have owned (wrote off my s15

The clutch doesn’t seem to slip, but it could be getting old? I have heard that there is some level of peddle adjustment that can be done but I can’t find a detailed picture filled guide or a diy fix. I was thinking about just having my mechanic install a new clutch for me as I would like a better than oem performing one anyway. I am interested in getting on the track this time. And I do like spirited driving. No major engine mods, just the fun stuff like full exhaust and intake. I am looking at this clutch here: http://www.mx5mania.com.au/product983.htm
Can I have my fly wheel machine to suit it? Or does the above link say that an already machine fly wheel being machined again to suit this new clutch will not suffice? It is a bit misleading. I am assuming that I can request my mechanic to set it up for a low down in the pedal friction point? What other bits and bobs could use an update and replacement while the box and clutch is out? I want to get as much out of this potentially costly install as possible (my mechanic is good and has only quoted me about 350 including machining of flywheel, loyalty discount I guess)
Any help would be realty appreciated, I have no mechanical experience when it comes to clutches and only basic knowledge of the install process for a clutch.
Thank you
