Yeah looks like a 0.965" telescope. You won't find any quality eyepieces for it.
You can buy an adapter, that will fit into the right angle diagonal, which will allow most (but not all) 1.25" eyepieces to work.
If you want to get the scope operational, I would buy these two things:
That being said, this telescope is essentially just a toy, so I would not invest much more money than that into it. It's money that could be spent a more capable telescope.
YMMV! Especially when attaching a DSLR to a cheap focuser with an even longer leaver
