Answer 1

actually centrino is a mobile intel core 2 duo processor. both laptops you gave have the same processor but the first one has a higher model on it. so i recommend you get the first one.

Answer 2

Centrino is a package of selected Intel motherboard, Wifi, and processor  (including Core 2 Duo series) ensuring that the components run with best compatibility. That Dell model use Dell's own wifi.

Enchanced mean that some of the processor and motherboard feature depend on each other, so theoritically they work better compared if they are installed in different spec.

I'll go with HP. It support the latest n wifi standard
