I would like to bring down the magnification to about 30x or 40x, so 20+mm eyepiece would be the right choice.
I have a few questions:
1) Would it make sense for a scope like this to buy a new eyepiece?
2) Would it make sense to buy a 0.965" to 1.25" converter and what is the effect on focussing (for example nearby, daytime observations)
3) What type of eyepiece is good enough for this scope?
I also wear glasses so eye relief is important.

1) If you have the right size focus tube (36.4mm) you can get an adaptor that screws into it and allows you to use 1-1/4" diagonals and eyepieces.
2) Get a hybrid diagonal and use 1-1/4" eyepieces.
3) Look on Astromart for some 0.965" eyepieces. With your f15 scope (910mm/60mm) you'll be fine with Kellner designs like the Meade MA. Some decent ones are for sale right now:
For Sale: 0.965 Kellner Eyepieces $17.00
Give us some more info on the scope and what you can spend and we can give some more specific recommendations.

It is an all metal Japanese scope and the label states the name 'Apollo' and the size (60/910).
I already have a diagonal (image upright but mirrored).
I also want to use this scope for daytime observations (more like 1 mile than infinite). Would I be able to focus when using a converter like Orion .965"-to-1.25" Eyepiece Adapter ?
Astromart might work, but I have to find a source that ships internationally (Europe).
