There are a few things you can do.

You can enclose it within HTML comments:

<script type="text/javascript">
<!--

if (foo && bar) ...

//-->

</script>

You can enclose it in a CDATA section:

<script type="text/javascript">
// <![CDATA[

if (foo && bar) ...

// ]]>
</script>

You can include in in a file instead:

<script src="foobar.js" type="text/javascript"></script>

I think the warnings and errors are important but not a lot.
If you extract any SEO report from a website you would see a section that calls out errors and validations on your site.
I have tried to remove them from my site. I had about 100 + errors and 80 + warnings.
I have come down to 30 errors and 3 warnings.
Its not difficult to remove them. Just that if you are not very comfortable with the code, fixing one thing may spoil others.

Check http://woorank.com
It would provide you a free weekly SEO report and list the errors and warnings.
Click on the warnings and it would take you to a page where it would tell you what is the issue and what you should do to fix.
With little implementation knowledge you should be able to solve them yourself.
