One of the fun aspects of buying used are the surprises. In your case, the locking levers on the tripod legs is known problem. That is a bad surprise. It's possible the seller was unaware of the problem.
The eyepieces I'm guessing were rolled into the selling price. They may have been a good surprise. Sometimes a seller will add up the value of those and add to the price. You have enough in different sizes, although I can't read the info on the tall one toward the left. A 32mm Erfle? An eyepiece around 28 to 35mm will be low power, and some designs will show a large patch of sky, called the field-of-view or fov.
The orthos sell on the used market for roughly $30 each. If the long one is an Erfle, on the used market those sell for $75 or $125, depending on condition. You also have a useable star diagonal.
I agree with Russ. Those eyepieces are fine. Down the road you might consider upgrading. Newer eyepieces and diagonal may show brighter, more contrasty images. There are also eyepieces that show a larger fov with the same magnification, which can be impressive.
The new tripods you found on Amazon are strong, sturdy and heavy. Buying used can save money, if that is important. Watch out for shipping costs buying used. Shipping rates for UPS, USPS, FEDEX have gone up so much, it may eat up any savings.
Here is an example of an early Celestron tripod, the "triangle locked" tripod:
Quite different, but set up right can be a very stable platform. The legs do not telescope. For storage they fold up. So you always have a somewhat clumsy contraption about 40" long. Once you figure it out, it becomes less clumsy. It weighs about 1/2 or a 1/3rd of the ones you linked to making it easier to haul around. Used tripods similar to the ones you found, if you prefer, show up used. (I almost never buy new... that's me).
Here is a result of a search for "Celestron tripod" on the Cloudynights Classifieds:
(they sell fast) I would avoid buying the same one you have, as those locking mechanisms are prone to breaking.
Celestron 99.999999% has no parts to fix the old tripod.
Celestron tripods and wedge should all be the same until you get to the "Nexstar era." The difference is obvious. I think Meade tripods should also work, but verify.
Motors. I think the company who the motors no longer makes them. But, again used is where you can solve that problem. I don't see a power cord. Did it come with one? If you need a power cord, ask here and I can point you to finding one.
The motors run on 120V AC house current, or a battery/converter that delivers that. To test the motors, plug it in, there is no on-off switch. Listen real close for any humming or motor sound, and on some looking at the motor from the underside of the round base, there is a little gap or window and you can see something moving.
Final test is to set the scope up, simply putting it on a table is fine, aim it somewhere, anywhere. Note where it is aimed. Come back in a few hours and see if it has moved. Oh, you need to tighten the clutches. If you don't know about the clutches, time to search for a tutorial or manual.
You posted this in the equipment forum. There is specific "Cats and Casses" forum that would be a better place to ask these questions.
