Hey... And Happy Holidays..........
Ok.. You can use either a Card Reader or the 'USB Mass Storage' Option.. It is the same procedure...
If you do not have a MicroSD Card Reader... Plug the phone into the USB port on your Computer....
Tap the RED END key to stop the Music Sync routine.... Tap Menu... Tap Settings & Tools...
Tap Tools... Scroll down and Tap 'USB Mass Storage'....
Wait a few seconds and the phones MicroSD Card will now appear in your 'My Computer' as a Flash Drive....
Place the .doc, .docx .pdf, .xls, or .txt files you want to read in your 'my_files' directory on the MicroSD Card..
To read these files from the phone... From the main screen.........
Tap Menu..... Tap Settings & Tools.... Tap Tools... Scroll Down... Tap * File Reader...
From here you should be able to select the files you placed in the 'my_files' folder...

If you need further assistance... please feel free to ask..... I will try to explain in a more detailed fashion...
