Keep reading the Wiki's -- the answers are there. Especially the articles oriented to beginners.
The "Solingen" stamp usually means a good razor -- good steel, properly tempered. The Germans didn't make bad blades. There's no "hierarchy" in razors -- "fancier" (and more expensive) doesn't mean "better shaver". If it's good, it's good, and your razor is perfectly OK.
Honing will be around $15 - $20 -- check the "Classifieds" here. You can learn to do it yourself, but it's a whole new hobby; try it on your _second_ razor.
You'll need a leather strop, to use before each shave.
Whipped Dog Straight Razor Sales sell's a "Poor Man's Strop Kit" which has a leather strop and "pasted balsa strop". That kit will keep the razor sharp for a long time, after it's honed. You can spend as much money as you want to, for larger / higher quality / fancier strops. But most of us damage our first strop, nicking it (or slicing into it) with the razor during stropping.
A brush can cost as much as you want -- $10 from drugstore, much more from specialty stores. Same with shaving soap.

PS -- There's a useful Wiki article here:
Brands of Straight Razors to avoid - Straight Razor Place Wiki
Your razor is _not_ in the list.
PPS -- There's a long thread, on this site, by a previous Mehaz owner. Be sure you read to the very end! --
