Be patient. You are not banned by google if you have pages in the google index. Put some good quality links to your site with your keywords as anchor text and wait. 301 redirect your old pages to new pages. Generate a sitemap and submit it to Google Sitemaps. Good Luck
Where did you hear that? 301 is a permanent redirect which tells the search engine that the page is permanently moved and new page should be crawled. Its 302 redirect you might be referring to which can harm your site. 404 is not the solution; though it may help visitors to locate the page they are looking for. You can't remove the old pages from google's index. They will go away once google find the new pages.
I also recommend spidering your site and looking for errors or possible duplicate content. I second the recommendation of 301'ing relevant old URLs to the new ones.
