That's not a modloader problem, it's Console and HeroesGuild that are crashing, go to the thread or site you downloaded them from and see if there's any solutions there. From what I see, modloader is working fine on your install, it's the other two mods that aren't playing nice.
Post modloader.txt, that will tell if the uranium mod is actually running. Plus, if it does what I think it does (adds uranium ore?) then you would have to travel to a completely new area of your map for the new ore to be generated in the new landscape, it won't just magically appear in an old area of your map. if you did that, then ignore that bit. TMI also seems to have problems with modloader for some people, I don't use it as CJB's item spawner works well for me, but other people say it works fine, so maybe there's some hints on the TMI thread?
minimap generator? That's not a Risugami mod, so go to the thread or site where you got that mod and see if there's help there. Not sure what new block types you're talking about - the light sensor or floodgate? There should be instructions in the OP for those.
Zip exceptions are almost always a problem caused by the archive program used. Try 7zip or winrar, and see if that helps, or use the texture patcher, it's a lot easier.
ModloaderMP is a different mod for multiplayer, go to it's thread for help.
Use the texture patcher to install mods.

Post modloader.txt or an error log. Or use the texture patcher to install mods.
