I am new and fed up and need help asap

I watched and taped Oprah a few weeks ago and want to take action.
Our house looks exactly like the house that they showed on the show.
I have taken all of the piles of clothing out of our bedrooms.
There is sooooooooo much and I am having an anxiety attack right now because I don't want to get my husband upset for getting rid of his things that I know he now longer needs.

One more funny thing. I live in Pennsylvania and you know how cold it is here.
Well, I have not been able to find my Winter coat until today when I brought all of the clothing in out bedroom out onto the living room floor.
That is so very pitiful to me. I was so happy to see my Winter coat.

Now, My question, What do I do with all of this stuff that is not mine that obviously does not belong on the floor in the bedrooms that is absolutely unusable.
I already know what to do with the stuff I don't need. I'm tossing it. But, I don't feel comfortable doing that with My husbands and my 2 boys unneeded clothing.

Oh. I would like to add that we also have a huge pile of clothing down in the basement.
I want to get all of this under control.

Oh gee, I truely hope someone is online that can give me some tips.
Thanks for help.
