Yes new tires are hard to fit and actualy I would say that yes, the old tubes would be too big to fit with 25c tires. A tube thats a little on the small side that inflates into the void is far more prefferable than one that's too large. There's a reasonable likelyhood that the large tube will remain kinked under the tire which will cause problems.
When you get new, smaller tubes then one of the tricks is to use TWO levers and procede slowly. When fitting a tire I put it on by hand up to the point when it gets too tight. Place both levers at either end of the bead that needs to be seated and lever both ends on. Then leave one end anchored and a few mm at a time slide the other lever along and lever on. If the lever comes out place it as close to where the rim and bead are meeting and lever it on. Do it carefuly and slowly and it will be on before you know.
When dismounting a tire I will start with two levers seperated by say 5 mm and lever off. Try and hold one lever in place and slide the other along although this can be hard to do. I usualy pull the levers right around inorder to get as much bead off as possible and this usualy works.
Also I only use plastic levers, the rectangular, yellow plastic sort. Mine are branded Michelin.
