I have some question for Messianics- Do you keep Yom Kippur?

Do you eat a 'Kazyit' Matzah on Pesach? Do you get Brit Milas? Do you have any restrictions on Kashrut? Do you say ת "s", or "t"? What Techelet do you wear if you wear Techelet at all(Kela Ilan, Radzyner, Ptil Techlet)? Do you learn from the Talmud? Do you have Sofer Stam Torahs, or just use like pen ink to write them? Do you have the Teffilin in the order of Rash"i, or Rabenu Taa"m?
