Welcome aboard Andy!
Sorry, no eyepiece guide. I'd go for (negotiate with dealer for) a comprehensive set of GSO plossls down to 12 or maybe 9mm, i.e. 32, 20, 15, and 12mm, and a 2x barlow: Orion Deluxe 1.25" (probably best value but hard to come by) or Shorty Plus (actually 2.2-2.3x) or better but dearer Televue 2x. Any leftover change, spend on Cheshire style collimating tool, Telrad, red torch, charts/guides. (Southern Sky Guide is a great starter and a bargain.)
Binos 7-10x power, 40-50mm aperture are also a must have.
