Make sure the Streak is off by holding the power button down for about twenty seconds. Then, get into recovery in the usual manner, tap volume + once, then press the camera button to execute a factory reset. Wait a few minutes, then hold the power button down for about twenty seconds to shut off the Streak. If you want to execute StreakMod's data wipe/factory reset, get into recovery, tap the camera button, tap the volume - button twice, then press the camera button. Wait about a minute, then pull the battery to shut the Streak down. Since you're selling it for parts there's no need for you to have it reboot.
Q: Can someone suggest a link I can follow that will walk me through the root process for this phone?
A: Simple answer is no. Do your homework. No spoonfeeding here. Check the stickies and the search engine. You'll find it soon enough.
