Quick and partial reply, and Chris can correct me later:
‘With your help we will stop using the labs tile service a month from now on Monday October 24th.’
Yes, "a month from now" = "in a month". ("In a month from now" is not a common choice in English, but it probably works well in other languages). Also, I like your your idea about adding a comma ("...from now, on Monday, October 24th").
"
Wikimedia Labs" is a proper noun/name, so you could leave it untranslated if you wanted. If you choose to translate it, then it would probably make sense to use the same word that you would use for
a computer lab (which might be the same word as a scientific lab, but I wouldn't want to assume that).
