I hardly believe that you can handle everything on Kash. There's plenty of content there tiered for the upper CLs. Do your COMPNOR missions now, while they still give 100% XP (worth one CL for the completion of the missions themselves; this does not include the XP from the NPCs/creatures). At CL70, that XP rate is reduced to 65%, and at CL80, reduced to 45%.
The Meatlumps Themepark is great for the mid-upper 60s.
*notes the date, well, if he's still in his 60s this is good advice!*
