I have lived through both of these and I agree with KP about the speech. Ease up for now. The speech therapy will help tremendously. Keep talking about what you do and what he is seeing throughout the day. My daughter started speech class at 2 1/2 and was dismissed on her third birthday. It was only once a week and her speech didn't really improve until about two months into class but it all came along.
Now the nose, he might be miserable because of a possible ear infection. Take his temp. Maybe a little baby tylenol or motrin to ease the pain. Warm bath, have him sit in the bathroom while you shower as well - more steam. Saline and suction is great if you can do it. This is out there but I have taken my daughter to the chiropractor and I really wish I had started sooner. Here's some info:

Hang in there.
