I would dump that dealer because he doesn't know what he's talking about. By today's standards a 640G HDD is NOT considered a "massive" drive. The fact that it's a core 2 duo doesn't matter as the processor doesn't know or care how big the drive is. The question really should be "How large of a drive do you need?" If you need to carry that much data around in your laptop, then go for the larger drive. Personally, the largest drive I've ever had in a laptop is 320G and have never come close to filling that. Your needs may be different.
If I was doing the upgrade, I would go for the 7200rpm drive but it's your money and your computer so if you feel the 5400rpm drive is best then go for it. Either will work fine.
I wouldn't worry about a single "Interface Communication Error" as reported by HDTune. If you were getting many errors I would be concerned. Regardless, do regular data backups and you never have to worry about losing data.
