Most scripting languages will allow you to do a 301 from within the script to the new location, so being static or not shouldn't be an issue.

As for the JavaScript redirect, it shouldn't really harm you, but the old page will most likely stay in the index for a very long time this way. Using a 301 will cause it to flush sooner and pass along whatever rank it had to the new page.

Yahoo told us as SES in Chicago that a Meta refresh with a time of 0 is treated (by them) as a 301, while a higher number of seconds they treat as a 302. Meta refresh may be a better option for you if you can't get a scripted 301 to work.
