G'day ya'll..

After purchasing a template for my new website I need to look at coding php the entire site.
What is the best way to setup this? I am running modernbill and vbulletin and would like the entire site to look professional and load very fast.
I picture the header and side links remaining the same for the entire site and yet updating these two areas easily.

Any comments or suggestions would be great. I am using editplus for programming and scripting.

Cheers and thanks for the replies.
