Pennzoil synchromesh works well for the trans oil too. A little bit cheaper and easier to get than MT90. The MT90 is great stuff though.
For bleeding I always do it with two people. One person pumps the pedal, the other works the bleeder valve. I'll say "pump" and the person inside pumps the pedal a a few times then holds it down. The person bleeding then opens the bleeder until the pressure drops off, then closes the valve. repeat. I also like to use a clear hose off the bleeder to a reservoir. This keeps air from being able to get back in the bleeder and you can see any air coming out along with clean fluid. They sell reservoirs for this on amazon for under $20. I usually make my own from a gatorade bottle(short and wide for stability) and clear hose. Just drill a close fitting hole in the top of the bottle for the hose.
For a person new to auto mechanics or even doing this stuff for many years, it's a good idea to take pictures of the brake set up before starting, like how pad retaining wire is installed to eliminate any confusion going back together.
The most important thing doing this job is constantly check the master cyl to make sure it never runs low! Once you get air in the system you are in trouble. Before starting I use a syringe to suck out as much of the old fluid in the reservoir as possible.
When buying the fluid, buy 3-4 small cans instead of one big one because once a can is opened it must never be saved to be used years later.
Follow the advice as to the bleeding procedure someone else posted, lt rear, rt rear, rt front and driver side last.
You may have an issue removing the rear rotors due to a lip worn in the outer edge of the rotors so that will have to ground away.
The rear brake pistons do not push back in like the fronts, they have to be turned in using the big X in the end of the piston. I had to use modified needle nose pliers to turn in the rear pistons for my first Mazda brake job. The pistons turn very hard by the way. After doing the job I bought this kit from Amazon for next time.

I made my own one-man bleeder many years ago that incorporates a check valve to prevent reverse fluid flow, however one can be bought at an auto parts store or Amazon if a second person is not available. You can get elaborate with a bleeding system that incorporates a vacuum device or buy one that simply incorporates a check valve to keep from reversing the fluid flow when pedal is released.
When replacing the rear pads on my MS6, I damaged one of the piston boots which is easy to do so be prepared and have new ones on hand.
To keep my garage floor clean I use a very large, lipped baking sheet placed under the work area to catch crud and any spills to keep the floor clean, I got mine from Sams.
