Hi, and welcome to the forum.
First, matcha equipage; it depends on how much money you want to spend. I agree with you, its best to have the chasen and what not for better results.
For pure function, this is a good, budget starter kit from Ippodo: http://tinyurl.com/3bd9s9
. I have not used it myself, but I've good things about it from other tea-chatters. (3,800 yen is about 35 dollars).
O-cha also has a starter kit: http://www.o-cha.com/green-tea/mancha-starter-kit.html
. Its a build it yourself sort of thing.
I'm sure there are other starter kits out there and of course you can piece it together yourself from items you like--this is what I did. A chasen and chashoku you can get from most places that sell Japanese tea. A Chinese made chasen is cheaper, not as nice, but cheaper, and can run you about 12-15 bucks. Japanese chasen are closer to 20-26. If you are looking for artisan bowls, places like Hibkiki-an, Artistic Nippon, and Zencha have nice selections, IMO.
Matcha: I think this is a great one to start off with: http://www.o-cha.com/green-tea/uji-matcha-kiri.html
. Its very good, fresh, and a great price. When I started drinking matcha, I jumped in and bought more expensive ones before I had developed my palate to the extent in which I could fully appreciate it.
I do recommend buying matcha only from Japanese companies and/or vendors you trust. Matcha has such a short shelf life, you want to be sure you are buying fresh product and not something that sat in a boat or a ware house for the last six months.
I hope some of this helps. Good luck!
