Can I ask why specifically the Glock ? Only as a pianist, you may get more joy from the Vibraphone, Marimba or Xylophone. The reason I say this is the Glockenspiel is more of a finishing touch, whereas the others have a greater scope and use as an independent instrument.
Tuned percussion is far from a cheap hobby, I enjoy my love of it through the world of Drum Corps and am very fortunate that my local Drum Corps are the current British and European champions. We get to take advantage of some very experienced teachers from the States where percussion education is in another league.
Scales, Arpeggios and Chromatic runs are your best friend as a keyboard percussionist, they are the best way of familiarising your self with the keyboard, enabling you strike the notebars with your mallets in the correct positions with a minimum of effort.
I agree here, I would suggest a xylo for Graded exams as its the easiest technique (No pedaling to deal with etc)
I would advise to get a teacher for beginning as you will need to be shown proper stick technique etc.
About an accompanist: some pieces have accompaniments you will just need to have a look at the AB books.
