Basset Hound Troubles

Question
Hello -- I purchased a female basset hound pup and am having two areas of great difficulty with her.  She is four months old, and spent the last 2.5 months in a local pet store, which likely is at least part of the root of her problems.  First off, she barks -- a lot.  As a basset, her bark is a loud, carrying, low, reverberating bark that literally shakes the walls -- she can knock pictures off the wall with her bark, no kidding.  This is especially bad at night.  I know the whole "don't give into it" bit, but I haven't slept a full night in two weeks.  She will bark nonstop for upwards of an hour or more.  I live in townhouses, and the neighbors have complained.  
Secondly, she is not "getting it" with housebreaking. I'll take her outside, let her walk around, and she'll do nothing.  She'll come in, and within a minute or so, she'll make a mess somewhere.  This morning, I fed her, let her walk around for 5 minutes or so, brought her back in and put her in her crate. Within a few minutes, she was barking loudly and I smelled the tell-tale smell: she'd pooped in her crate.  

I've tried everything to encourage her to go outside. I bought the spray you use, I bought a "pee-post," and the crate.  The cost of housebreaking her is quickly overrunning the cost of the dog, and I'm at my wit's end.  Help, please!

Answer
At bed time, with a new puppy, I have found lying down in front of the crate like you were going to sleep and speaking softly to it, or singing, until it settles down and goes to sleep works very well.  Follow the pattern, a period of active play, outside to eliminate, and then into the crate.

As for the housebreaking, you need to outlast her outside.  Keep on walking.  keep her moving except when she stops to sniff.  Eventually she won't be able to hold it any longer.  Then praise her.  Don't cut the walk too short.  Likely she will enjoy the walk, and you don't want her to catch on to relieving herself ends the walk.  You may want to frequent areas other dogs use, a tree all the males mark, etc.  There is some danger of disease that way, but you have to get her to go so you can praise her for going outside.
