I have a server that is running SQL2005 and has been a long while.  I just found a need to install express 2008 so now they are both on that same server.  Is there any reason to move the data from the 2005 server instance to the 2008 express server instance?  Any downside?

There is no downside besides some added effort.
There is no reason as long as you do not need to use any of the new features - which is unlikely -, or want to get rid of 2005.

Not to mention that SQL Server Express only supports 1 CPU and 1 GB memory.

You should run both side by side because the standard and enterprise edition of sql 2005 has alot of features that are not in sql server express.
1.sql server 2008 express cannot be a publisher in a replication scenario.This is important if you want to set up replication.
2.number of CPU's supports -for sql server 2005 standard 4 cpus are supported and for enterprise -the number of OS cpus is supported. Express only supports one CPU -this is important with performance in mind.
3.sql express supports only       1 GB of RAm while sql server 2005 standard  supports the OS maximum.

For a complete comparison,look at this:
