.no worries Copernicus. nice that tracking came with your mount also, but at most, you will probably get 30sec - 1 minute worth exposure on that mount. Its not stable enough for deep space stuff but you might get away with planetaries. To go longer exposure, you will then need autoguiding with a more suitable mount such as HEQ5 or the EQ6 and a guidescope attached with a guide camera. Sorry can't help you out with eyepieces as I'm no expert, but any Televue, Pentax's, or Vixen LV's should do well in that 8" F/4 scope. expect $150+ each for decent quality eyepieces.
