We use Yahoo IM and Google Talk and Blackberry IM without the full data plan and never had a problem. To use the instant messaging you do not need the full data plan, if you have unlimited text/IM/MMS and the email data plan like we do, it is included with Tmobile.
Now, to get Yahoo IM on your 8320, you'll need to download it via wi-fi, or switch to full data plan just for a day in order to download it, then you can switch back. Thats what I do when I need to download something OTA
I hope this information helps you, good luck
