If you were on a Mac, you’d be good to go with the default configuration – better than Music CD quality – but if you’re on a PC you might want to reconsider the sound card. They’re not winning any awards for sound quality given that they’re in a noisy computer and are generally considered a throw-away item (unless you personally bought an expensive one).
We reviewed some USB devices and the UCA-202 comes to mind.

Past that, you dub like you’ve been doing it since 1947. After installation, click once inside the Audacity red recording meters and they will wake up and present the “E to E” sound for monitoring. Play the loudest part of the tape and set the volumes for about -3 to -6. Re-rack the tape and go.
One significant different is the meters. Audacity meters are dBFS peak, not ANSI 16.5 VU. You May Not Hit Zero. Ever. Zero on the Audacity meters is where permanent and obvious sound damage will occur. If there’s tone on the tapes, set that for -12 to -15 in Audacity. If you’re transferring to broadcast, set the tone to -20 in the US and -18 in Europe and export from Audacity at 48000, 16-bit, Stereo.
Export as WAV at the end of each tape – always, and make safety copies. Audacity will not “Save” a sound file and you can’t move an Audacity Project.
