Hi Eric, the other eypeices are to increase magnification but to be honest other than the 12.5mm they will be unusable unless the scope is motorised, the erecting lens is for daytime use it will put the image the right way up (not required for astronomy) the barlow increases the magnification of your other eyepieces (eg: 20mm becomes 10mm if 2x barlow) again unusable unless motorised. we tend to use the lower power (20mm) to help spot objects and then up the power for closer views.
Hope this helps
Brendan
