Same answer from me- I run what I affectionately refer to as the Lucky Dog clutch combo- Luk + Fidanza
Luk manufactures the stock clutch and pressure plate, so when you see the luk clutch referenced it's actually the stock clutch, just purchased anyplace BUT the Mazda dealer so that the price is significantly more reasonable (cheaper). The Luk clutch is used in a variety of things so feel free to shop around for the lowest price you can find- mine came from ebay - you're searching for a Luk 10-064
The stock FW is a dual mass unit, and most places will not resurface a DM FW. Some do, but they are few & far between. Also, the springs that allow the DM to function tend to wear out starting around the mileage you're at now, and in my opinion you would be asking for trouble to continue using your stock original FW even if you can get it resurfaced. Replacement DM FW will only come from Mazda, and is very expensive- IIRC it's priced around $1100 from your local Mazda parts counter, and that's only the FW.
Considering that you can get an entirely new clutch & FW setup for significantly less than the cost of just a new Mazda DM FW you can see why changing to a different FW is a very popular option. Fidanza is by far the most popular option when collecting your own components separately. There are, however, a few other options from ACT and others- but the Luk is the only one that will give you the stock pedal feel.
So, common options-
Luk Clutch- cheapest you can find, but ballpark ~$250
Fidanza FW - ~$340
You can shop Speed 3 clutch stuff too- it's the same as the 6 and sometimes easier to find.
Act, for normal street driving you want to stay away from the 6 puck & other fancy ones, and go with the Street kit. Lots of folks will say they like their 6 puck and that it's very streetable, but it's a short lived clutch, lasting often only around 20,000 miles.
Better to look at this for street daily driving.

If you launch or drag often, or otherwise have issues with the stock clamping power then by all means consider a heavier duty clutch like the 6 puck.
My power levels vary between 325 and almost 400 hp, and the Luk has been good for me, but I'm a soft touch on clutches, always have been, and I don't launch all that often and almost never repeatedly. Random hustle from a stoplight and autocrossing is about it for me.
