Here's the tracklist for this CD, from an 2019/11 auction. It is printed on the extra pamphlet where the CD sleeve is sticked on. There's even track timings.
As for Vol. 2, to make it short: there is no most likely Vol. 2. Perhaps it was intended to have a second volume or it was misprinted Vol.1 on the disc (some guide books have 2 cds in one or 2 separate volumes). Neither Nintendo nor Enterbrain websites have ever mentionned a second disc, only disc.
