Renew passport with visa

My wife's passport will expire in May 2013 but we are planning on going to Spain at the end of December.

I read that you need a passport with at least 6 months validity so I'm wondering if she can renew it earlier (October/November). Also, how will that affect her visa?

Does she have to contact United Kingdom Border Agency before renewing her passport in the Philippine Embassy in London or does she have to carry both passports when she travels? (The old one with the visa and the new one.)

UPDATED QUESTION:

Thanks to the comments and @Ankur's answer. Now my doubt is if she can she renew the passport more than 6 months before the expiry date.
