Thinking of buying Belkin Pre-N Router and Card for laptop. A few questions please.

I am thinking of getting a Belkin Pre-N router and wireless notebook card Like the one on this site http://catalog.belkin.com/IWCatSectionView.process?IWAction=Load&Merchant_Id=&Section_Id=202570

Is this setup faster then a wireless linksys G Router?
Will the distance of the Pre-N live up to it's advertizing?
Will I be able to secure my Pre-N wireless network?

Any other points you would be able to inform me about Pre-N?
