I bought DLC′s and Steam installed both automatically. I have some mods (MMM and FWE included). Should that be a problem. I mean should those DLC have been installed before the mods? Or it is right activating FWE and MMM plugins related to those?

FWE and MMM will ask you to install plugins that have their mods incorporated with the DLCs, like spawn textures and weapon replacements. Just look over the descriptions of each page (MMM and FWE) they will provide links and compatibility patches. In almost every case, DLCs will either not conflict with a fan mod or the fan mods will require the DLCs.

The dlc's get installed with the main game so just activate your mods and compatibility patches after as usual and use boss to sort your load order out.
