I have ISDN PCI Card in a Server with Intel xeon 64 with VT.

How can I use this PCI Card?

I guess you want to use this PCI-Card within the Windows Server 2003?
Well that won't work! The PCI devices can only used by paravirtualized guest not HVM guest. As there is some development in this feature, maybe someday one could do it, but not now!

Check this for further information:

Or, how can I use a USB device (external Hard disk)?

I have never really tested it but there is a way!
First of all you have to check wich ID your USB-device gets:

# lsusb

Then you have to add 2 lines to your hvm-config:

usb=1
usbdevice="host:xxxx:yyyy"

where xxxx:yyyy is the "ID" section in lsusb. I can not tell if this works with usb-flash-drives too, because I would think that there is some heavy load and maybe therefore it won't work.

How can I the partisions (for the virtual Harddisk) change (make a 5 GB Harddisk in a 20 GB Harddisk)?

You want to resize the domU harddisk? Hm, never tried it too, but if you use LVM in Dom0 and giving a lvm-partition to the domU, you could try to shutdown the domU, resize LVM partition and then, after starting domU again, try to use Partition Magic within domU to resize your filesystem. But, never did that too, and I don't know if it would break your filesystem?! So be carefull!

Can I save the doms file System in the Linux System?

You can make a 1:1 copy of your image file, with cp or dd, I guess!?

I can not find the image files for the doms.
Check your domU config-file, there you should find the path to your image file.

Hope it helps
