Installing Drupal

So I'm installing Drupal 7.0 on our server (web hosting hub) and I get to the end and i am greeted with these errors:

Warning: rmdir(/tmp/update-extraction/adaptivetheme/adaptivetheme_subtheme/css/ie) [function.rmdir]: Permission denied in drupal_rmdir() (line 2277 of /home/innods5/test/includes/file.inc).

I'm helping a friend setting up a new site. I've used Drupal 6 on my site previously.
The ISP said they installed Drupal 7 on her site, but it still seems to default to using "home.html".

They said to use "http://{sitename}/?qmin" for the initial admin logon - but that just takes me to home.html.

I tried specifying index.php, and that brought up a "Page Not Found" page, with the Drupal login panel. Entering userid/password there and pressing the Log In button takes me back to Home.html (with the URL being: "http://{sitename}/?q=index.php&destination=index.php"

What is the best free web host to install Drupal on?

Greetings,

Hoping for some help with an install of sorts. Will really appreciate any input, suggestions, etc as while I'm a complete Drupal believer, I'm a low-level user (not a developer) which will soon be made apparent. Here's the deal...

I initially installed Drupal via hosting company's add-on applications to run a subdomain of a site. I now would like to run the entire site -- main domain, the existing subdomain, and other subdomains to be added in the near future. My problem is that Drupal was installed in the subdomain's directory: /var/www/html/subdomain/drupal

Recently I was asked by a client to pickup hosting and maintenance on an existing Drupal 6 site. The previous hosting company gave me a backup of the files and a SQL export from the database. The SQL export was performed from within the database, so I had to first create a blank database. I almost exclusively use phpMyAdmin for any MySQL tasks, so this solution will reflect that method.
After creating the blank database on the server, I clicked on the database name then clicked the import tab. I browsed to the file, made sure the SQL format type was selected and clicked Go. After several minutes MySQL kicked back and error that looked something like this (I shorted the error at the ellipsis):

Error
SQL query:
INSERT INTO `users` VALUES (0,'','','',0,0,0,'','',0,0,0,0,NULL,'','','',NULL,'',1),(1,'siteadmin' …

#1062 - Duplicate entry '1' for key 1

After some research I learned that the auto increment setting on the users table UID field was the cause. Some more research and some trial and error, I realized I needed to change the uid field settings in my exported SQL file for the users table from this:
`uid` int(10) unsigned NOT NULL auto_increment,
To this:
`uid` int(10) unsigned NOT NULL default '0',

as a newbe, I have a few questions

my shared hosting for drupal is on unix with their "1 click" install of drupal 6
they do not support drupal on windows

1. can I upgrade to drupal 7 after installing the 6 or must I install by hand

2. can I develop drupal 7 on a windows 7 machine local and ftp to the unix shared hosting

3. what about addons ? can I add on win 7 dev machine and ftp to unix
