yes, it does not sound good for focussing, where did you get your scope, what brand eyepieces.
are the eyepieces all the way in?
the 25mm will give you a wider view ie less magnification. divide the mm ie 25mm into the focal length of your scope (1000mm i would guess for yours) to get magnification.
are you more interested in planets or deep sky stuff.
a barlow will magnify your view, but without tracking, it can get out of hand pretty quickly. with say an orion shorty plus barlow 2x

will turn your 10mm into a 5mm.
most guys seem to have a 10mm and 30mm, add a barlow to this at say 2x, then you get 5mm, 10mm, 15mm, 30mm.
i have not bought a barlow yet as i do not have tracking, i went for a ultrawide 30mm 80 degree from
