First of all, excuse my English.

I have installed MCM 1.5 to be able to configure oHUD, Radar Mod and some others, but every time I start a game I get a message "Mod Configuration Menu had been installed" and all my setting for these mods (radar position, compass, AP and Hitpoint indicators) are resetted to defaults. I disabled all additional mod except Project Nevada, MMUE, MCM, uHUD and Radar Mod, but it doesn't help. I tried to reorder mod some ways, but no luck too.

Maybe, I have to install these mods in some "right" order? If so - which one?

I believe it's supposed to do it that way. As far as I could tell, there's no way to save your settings, you need to manually select them every time you start a game.

I don't think so because settings for Project Nevada or Quick Trade mod saved persists between game runs. The real problem is a settings for misc. HUD mods like oHUD and Radar mod.
