MCServer can be a little unstable. Especially if you have entities or simulators enabled like redstone. Badly written plugin's can also cause a crash, so it's worth to test some plugins first.
I'm afraid you can't use the plugins and mods from Bukkit or Spigot. It's not only that the language is different, but especially the architecture. If you want a mod or plugin from Spigot/Bukit/Vanilla the author (or somebody else) has to completely rewrite it as either a Lua plugin, or integrate it in the server itself.
