So long you do not change the functional level, the trust should remain.

The DC Upgrade itself is not an issue.

You can upgrade the DC and also change the Domain Functional Level to 2008 R2 if you want to but not the Forest Functional Level, if your trusted Domains are still on older DCs and in the same Forest. Otherwise you could upgrade the FFL as well.

Currently the Windows 2003 DC are not raised to the 2003 DC forrest functional level. They are in the 2000 Forrest Funtional Level.  Should I raised the forrest functional level to 2003 on my Windows 2003 DC environment and then keep my new Windows 2008 R2 DC at the Windows 2003 Functional level?

Yes, this is an possible solution, but you won'T be able to use some of the 2008 R2 Features like DFS-Replication or AD Recycle Bin unless you upgrade DFL to 2008 R2.
