cable basic's?

Hi >>

firstly i have to admit i am a cable virgin, so this may seem basic, i just got a panasonic TH-42PX80B and the sony dav-is10. So basically i want to know what other cable( i need, i have no plans to get HD via either sky or freesat, but have normal sky and an xbox. im not looking to spend alot or have tons of different cables just an all round simple solution. Many thanks
