My site is using drupal and my theme is designed in a way that code of both sidebars comes before the code of content is it ok
If possible than try to get your content first as i will be crawled before other scripts. one more option is there.. u can put that scripts to one file and upload it but i m not sure it can be done in your case or not.
Bots crawl from top to bottom, therefore try and get your most important content containing your keywords / phrases to the top of the source cod e(ie. top of the page)
