Need some Magento fixes to existing site

We just ran an SEO analysis on our Magento site and have some serious configuration issues that we need to get fixed ASAP. We are running Magento 1.8.1.0. The fixes that we need done ASAP are as follows; - There is some extension installed that is generating multiple H1 tags for all pages and setting the H1 tags to DEVELOPER TOOLBAR. Need this disabled/removed - Need a recommendation for [login to view URL] configuration as it looks like there are cache files being scanned, product_compare urls being scanned, ie: dynamic pages. I think this can be fixed through the [login to view URL] file but want to confirm - It appears as though there is a print view URL that is being automatically generated by Magento that is being indexes as well. Need this excluded. (This may just be a [login to view URL] issue as well - Need to know how to create an html sitemap to include in the site footer - Canonical links are not setup properly causing many pages to not be indexed. We are also having an issue with our Wordpress configuration where the blog body is being included as an H2 tag. If you can fix this too that's great but it's not a Magento thing so not crucial. I'll give you access to our development environment and once all of the fixes are complete, I'll promote them to production for testing so I'll need to know exactly what's been done so i can review the fixes before promoting to production. Any other suggestion for SEO tweaks will be appreciated but not necessary.
