Well... no one eyepiece will do it all, even with a Barlow or zoom. You need to look at what focal lengths you want in your eyepiece set, aiming for steps between them around 1.5X (a set of 4-5 ep's) or 2X (set of 3 - low, medium, high).
Your scope can usefully span a range of eyepiece focal lengths from about 40mm (I'm thinking of my 2" TMB) down to about 8 or 9mm, a span of 4X from high to low.
If you want to build around the Meade 14mm, a simple set would be one eyepiece around 28-30mm for low power and another at 8-9mm for high power.
My pick for the low end would be the 30mm TMB (find one secondhand on Astromart) or Vixen NLVW 30mm. At the short end, a mid range eyepiece around 8-9mm would do fine, my pick would be a Vixen LVW8mm or a Panoptic.
If cost is a consideration, I'd choose a 9mm ortho - not a plossl. If cost is no limit then go for a Radian, Nagler or Ethos.
