Sounds like you need HTTP POST's
I recently wrote a script to simulate some web transactions recently (not too different than yours), I had good luck following this tip from curl's website (hxxp://curl.haxx.se/docs/httpscripting.html):

Quote:
4.5 Figure Out What A POST Looks Like

When you're about fill in a form and send to a server by using curl instead
of a browser, you're of course very interested in sending a POST exactly the
way your browser does.

An easy way to get to see this, is to save the HTML page with the form on
your local disk, modify the 'method' to a GET, and press the submit button
(you could also change the action URL if you want to).

You will then clearly see the data get appended to the URL, separated with a
'?'-letter as GET forms are supposed to.
If there are 3 clicks, then there are going to be 3 separate curl commands. You should be able to avoid the first "click", because you'll just be uploading the file in step 2, no need to browse to the first page once you figure out the URL of your POST.

I'm making up examples in as I don't know what your actual HTML form looks like. The trick is figuring out the form query variables (order matters!!) and converting that into your curl command-line arguments.

Code:
#/bin/sh
# 1.  Get page - probably not required
curl http://www.mysite.com/mypage.htm

# 2.  Upload file - most likely a multipart form.  the '@' means upload a local file
curl -F "upload_filename=@/full/path/to/local/file.txt" -F "myotherqueryvar=queryvalue" \
-L http://www.mysite.com/upload-page.htm > html_out.htm

# 3.  Parse HTML - you'll basically have to look at the return page
# and see if you can figure out a pattern that will grab the link.
mylink=`grep (insert pattern here that will get your link) html_out.htm`
curl ${mylink}

Not sure if you can just supply the actual website... might be easier to give you the exact commands.

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default
