You don't have to if you have made small changes but if you make large changes to you site it isn't a bad idea to resubmit your sitemap

 

No. Just keep the sitemap file updated. Google automatically crawls the sitemap and updates it.

 

Thanks, I will check info in webmaster tool

 

re-submit doesnt hurt your website, and i did it many times (as google webmaster has "resubmit" button )

 

Yes. You should resubmit the xml sitemap if there are some changes.
