Ubuntu 9 codecs help?

After installing the os, everytime i was prompted to install codecs i installed only the the pack that was needed to play specific file, same about flash and java. Now i removed 3 packs because i wanted to install Ubuntu restricted extras. Also removed the java and flash. So, after installing the restricted extras i noticed tgat video quality is not as good as before. I removed the restricted extras and now i want to install every pack one by one as i did in the beginning. What i m concern of is the mess that all my exploration caused. Using Deborphan (orphaned package renover) find a lot of other packages that im safe to delete but im not sure about. What to do? Do i need to install all the codecs and then run Deborphan or run it now before installing the codecs??
