Internal Linking Strategy

I wanted to know if I need to keep the same internal linking strategy to keep results. I am going to keep the same page names so I dont have to worry about that. My site does well in the usual Search Engines, but I do not think it brands my company well, so I need to change the look. I also have learned so much on SEOCHAT over the last year that I know I can do way better. Anyone got any questions or comments.

you should be able to change your linking strategy without hurting results - in fact, you might even get better results. as long as you aren't changing the filenames or directory structure, you should be ok. of course, you may change how your PR gets distributed within the site, but that may be something you want.
