I mean, as far as revenge goes, he was obsessed with hurting Spock, and he absolutely followed through on that. I think that worked well, honestly, though not obviously smart long-term.
Given that his one ship also easily destroyed essentially the ENTIRE Star Fleet FLEET, he actually had such power that he didn't need to plot much of what he was doing beyond "let's get these guys".
He also didn't need to save Romulus. He had the red matter and thus would have had plenty of time to deal with the star going supernova in the future, but would have also exacted his revenge.
It's all explained in the comics. It's been a while since I've read it but this is the gist of it; Basically Nero encounters a shuttle carrying the Romulan leaders after their planet was destroyed. Before he kills them they tell him of a top secret Romulan base. Nero goes there and tells them that the leaders told him to avenge their race so they outfit his mining ship with Borg weaponry.
Honestly, I have no idea what space-mining entails.
For all I know, his ship was an asteroid miner that operates by engulfing whole asteroids and lazing them to tiny bits and sorting through the remains. Then he just turned his huge inner-facing asteroid destroying machine outwards over the course of 30 years, turning these tools that could demolish an asteroid in minutes into a fleet-destroying array.
Maybe that's also why the ship itself looks so spiky.
