I am in my second play through Skyrim. I am trying to catch all the things I missed in the first play through.
But this play through I completed Blood on the Ice quest first. It was bugged in my last play through.
My one miss was this link, I need to finish 125 Delvin and Vex quests to get a safe in the Guild along with the other models on display.
Let me explain, my last play through I was unable to purchase Hjerim (sided with the Imperials + Blood on the Ice quest never triggered.)
I plan on siding with the Imperials again this time also, but after the main quest.
My question is I have been asked to plant evidence by Vex into say Clan Cruel-Sea, or Shatter-Shield for that matter, if I do that, will it break something further down?
Will my choices to help Delvin and Vex plant evidence in Windhelm affect any further quests in Windhelm?

No, the radiant quests don't affect anything else.
I can not find definitive evidence of this anywhere, but I have done tons of radiant quests for people all around Skyrim and haven't run in to any problems.
I think the basic understanding here is that there are ~infinite radiant quests. And as such, they can not all be intricately connected to all the other story lines. Each individual radiant quest is just a one-off thing that by itself won't affect the rest of the world.
