Marie, sometimes the import is a breeze but in some cases it really is a pain. Sorry you are having so many problems.
Can you ask the hostgator folks to reset you account (just to make sure there are no ghost wordpress installs, as they are expensive) and just start from the scratch?
Some other things to try
1) Don't install wordpress via fantastico. The updates are not stable via fantastico. Do it the old fashioned way by ftping or uploading the wordpress install manually.
2) Are you using the "new blogger"? The import doesn't work with the old blogger.
3) You would have downloaded the blogger blog. Some times if you are moving after a couple of years with posts and comments, it might time out. The downloaded file is an xml file. So you can open it in a text editor and keep the structure (all the headers and closing tags), but just keep one post and see if it imports fine. If it does, then you have to manually split the files into multiple chunks and upload them one at a time.
4) Convert the blogger file to wordpress file outside of the import plugin. You can do that here http://blogger2wordpress.appspot.com/
Install wordpress and then import the wxr file. Sometimes that works better than blogger2wordpress plugin. This way you don't have to connect to blogger and authenticate.
5) If nothing works, try creating a wordpress.com blog, import from blogger (much stable and a beefy hosting), then export the wordpress blog, import it to wordpress. Time consuming, but sometimes necessary.
I am fighting with a conversion myself. How much ever I try the labels won't import. DO NOT change any url structure unless you are perfectly sure everything is as you imagined.
Hope you get it transferred fine. Once you move to wordpress, you will start liking it.
