Keep a watch out for a better price. Don't have an Ebay/Paypal account? Make one! Can't make one? Find some one who has one! I bought my Q3 for $4USD and it even cam with a manual!
Use this to Google downloads (e.g. pak0.pk3 inurl:baseq3 intitle:"index of"), err, check your legit installation Don't forget to download ioquake3 with the "Data Installer".

I don't know if anyone was successful at getting WQ3 running with OpenArena, but I know some attempts were made. Honestly, SG1.0 is basically the same as WQ3 2.2. We fixed the knife bug, changed some names. I don't know how much work was done with the engine.
Install ioQ3. Download openarena & extract pak0.pk3, then put that pak0.pk3 in the baseq3 folder of ioQ3. Then install the WQ mod. You may be missing a few textures, but this will probably get it running. Like Pardner said, WQ 2.2 is a downgraded version of SG 1.0 & I'm not sure why you'd go through the trouble for that.
WQ 1.2 on the other hand is worth seeing for nostalgic reasons, just because it is so different.

They aren't scaled correctly. In other words, the player models look too small compared to the world around them. It was ICI's decision to leave these maps out of the WQ3 2.0 release.
