Help please if you know guitars (fenders specifically)?

I'm buying a new guitar soon and I have no idea what I'm doing well please bear with me 1.) I want to know if these are the same guitar models (ie, Standard Stratocasters?) 2.) if the purchase would be worth eBay off, you see it in good condition, etc 3.) if the guitar on eBay is authentic, I guess saying that the serial numbers? anyone can confirm this for me through their experience http://www.guitarcenter.com/Fender-Standard-Stratocaster-Left-Handed-Electric-Guitar-501159-i1431993.gc VS. http://cgi.ebay.com/Left-Handed-Fender-Stratocaster-/120606622182?pt=Guitar # Ht_500wt_1154
