Safety Glasses: Polycarbonate, maybe? Wraparound lenses, probably. (I wear my regular, plastic-lens eyeglasses when shooting.)
Ear Protection: Find muffs with the most noise reduction you can afford. Some people use both plugs and muffs. (I use only plugs: Most of my hearing is already gone.)
Gun Case: Don't merely leave the cleaned pistol in its case, because it'll rust. Put rust-preventer chips or paper in there too. Check the gun frequently.
Bag: Should easily hold muffs, pistol case, ammunition, and a bag for empty cases. Maybe a simple cleaning kit, too. (I use Dillon's "Border Shift" for loaded rounds and empties.)
Open Chamber Indicator: Never used one. Slide-stop lever is enough, because open slide is pretty obvious.
Cleaning: A bore snake and some Hoppe's #9 or Ballistol does the job at the range, but a rod is useful if you ever have a squib load and a stuck bullet.
Magazine Loader: I've never used/needed one. But I shoot with single-stack magazines only.
If you want to use cheap practice ammunition, buy factory-made stuff because its quality is predictable. Bulk bags from the local gun store contain stuff of unknown quality.
Russian-made ammunition has the reputation of being dirty. Some people also don't like Russian steel cases.
No personal experience, but reports tend to make me counsel staying away from Taurus pistols: Bad quality control.
