Im not sure if I have understood you correctly but are you trying to transfer your blog posts from the .com site to the new one? You can’t actually incorporate your existing .com site to the new one as far as I know but you can transfer over all the info after exporting it and then importing it to the new site.
In .com go to Tools/Export and use the free option. Go to tools/import in .org and you should see an option to help you transfer over the info.
Make sure you backup your new site prior to doing the above just in case there are any issues with the import.
