As for Shinzon being a "known warrior," you'd think Section 31 and the Tal Shiar would have some opinions about a cloned Starfleet officer who's rallying slaves around him + building a super-weapon. I'm thinking the opinions would be something like "eliminate it ASAP."
Since Shinzon had built alliances within both the Romulan Senate and military, it's likely he built them within the Tal'Shiar as well.
What Shinzon did probably took years of planning and behind-the-scenes dealings.
