Welcome to IIS
I agree with Eric: continue until you can get the best out of your existing equipment.
Start with the 20mm eyepiece (don't use the 2x barlow). This will provide the lowest power and the brightest views. Collimation and focus will be more challenging with the 9.5mm.
Are you able to focus on a distant mountain in the daylight using just the 20mm eyepiece? If so, you should be able to align the finder. Then try to focus on the Moon (again, just with the 20mm).
Hope this helps and keep asking questions. The more specific, the better.
Have fun,
Doug
