I read these posts and smile. Mr DP you are so so new at this.
Planetary observing is a fine art and Mike and others have made points on seeing and experience.
My friend you worry about eyepieces to much. Some guy overseas does the same thing.
A few points to help you. Stop worrying about eyepieces. A good quality eyepiece will do fine. Buy what you can afford.
Then look at getting up in the mornings to observe the Planets. The seeing should be better and the scope will have cooled enough. Leave the scope under the patio or something if you have one. Make sure all the workings of the scope are fine , collimation etc. Sit down if you can when observing and get relaxed. Try your left then right eye, you may find one works better. Find the right focus. Use the most magnification your seeing lets you.
Then just look 10 minutes 20, 1 hour as much as you can. Sketch what you see. This will help you see detail, but only sketch what you see!!
Don’t do this one night do this when you can. The more you observe the better you will get. Next time we meet at a Star Party you can then show me what you can see. I will enjoy reading posts on what you see.
Take you pictures as well. This will get you better at using your scope. After you take your pictures take the camera out then put your eyepiece in and observe for a while. Your pictures then will be more appreciated by YOU.
Enjoy your work.
