the majority of the files that I'm going to move over are on my main system, which is running the 64bit edition of kubuntu. the box that I'm making the media server is running a server installation of ubuntu (no gui, base packages, etc).
on both boxes I have nfs-kernel-server and portmap packages installed.
on the server box I have edit the /etc/exports file to look like this:
noah@scarlett:~$ more /etc/exports # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). /home/noah/media 192.168.1.103(rw)
I have edit my /etc/fstab on the client box to look like this:
noah@lindsay:~$ more /etc/fstab # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/sda1 / ext3 defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid,nouser 0 1 /dev/sda5 none swap sw 0 0 /dev/hda /media/cdrom0 udf,iso9660 user,noauto 0 0 /dev/hdb /media/cdrom1 udf,iso9660 user,noauto 0 0 /dev/fd0 /media/floppy0 auto ,atime,noauto,rw,dev,exec,suid,user 0 0 /dev/sdb1 /mnt/storage ext3 ,atime,auto,rw,nodev,noexec,nosuid,nouser 0 0 /dev/sdc /mnt/usb vfat ,uid=1000,gid=0,noauto,rw,nouser 0 0 192.168.1.110:/home/noah/media /mnt/media nfs rsize=8192,wsize=8192,timeo=14,intr

after I try to copy (whether through konsole or konqueror) and it is sitting there stalled, I can no longer cd into my /mnt directory (the nfs drive is mounted at /mnt/media), but I can type in the full extention of my local harddrive mounted at /mnt/storage and access it fine, but if i try to go to just /mnt it stalls and never displays.
in order to gain access back to the mounted drive I have to reboot the client side (the server side still seems to remain functional), on which the drive is remounted and I can then navigate through the drive, make directories, and remove directories again, but if I try and copy a file, the same thing happens. any ideas?
You might want to check the permissions on the drives you're trying to copy to. You can create all kinds of problems for yourself using NFS is the user IDs on the server and client dont match. If you, for instance, used 501 for you own user name (see in /etc/passwd) on the server, but 502 on the client, but with the same username, you could find you dont have permissions on the client to write to a directory created on the server.
Also check that you've restarted the nfs server process after making changes to the /etc/exports file, do the same at the client (re-mount) if you've changed /etc/fstab.
On my nfs server, I use the following kind of entries in /etc/exports and I have no problems:

how to configure for nfs users
I have ubuntu installed on my desktop. How can I configure it to validate the users defined on nfs? I tried lot of things but no luck.
You need to ensure that all the UID/GID pairs for your users match on the server and on the client. The normal way is to have account authentication provided in one place - normally on the server.
There are several mechanisms; I use Fedora Directory Server to provide single network accounts for each user that applies to both Windows logons (using a Samba Domain with LDAP backend) and linux logons (using LDAP).
You could also try authenticating using OpenLDAP, or even just installing the old and reasonably insecure NIS/YP system to provide lan-wide password authentication.
