Glad I could be of some help.
Your going to most likely smell some coolant for a bit. After an issue like that and then having coolant all over the place it's going to burn off hot part's in the engine bay for a good bit. It's nothing to be to worryed about.
Most likely reason you heater is still blowing cold is due to their being an air pocket some where in the system. You can go about taking care of this issue one of many way's. Best way to refill a cooling system and be about 100% postive you wont run into an issue is by doing so with this item here.

That's how I do all the system's I open up and it makes it breeze.
Here is also a link to explain a good way to go about this issue your having as well.

You may have to do this a few times to get the air pocket worked out of the system.
Also if you look at the top of the t-stat housing you will see a small bolt in the top of it. Losing that up and crack it open, that is also a good way to get air out of the system as well.
