Colimation should be a problem with either scope. Are these Dobsonian or EQ mounted. The 10" will be your best bet. It's bigger, you'll see more. A barlow lense will double the magnification. Your talking about a short focal length scope so you won't get real high magnification. A smaller eyepiece will do the same thing. It's nice to have a barlow, but you don't really need it. A good 32MM for even wider views is always good. A smaller eyepiece for close ups of the moon and planets is a good idea, maybe a 7.5 or 5MM. Most your viewing of deep sky objects will be done at low magnification. High magnification dulls and dims the image. A smaller sharper image is better on most deep sky objects. Of coure use high magnification from time to time to take a closer look. A nebula filter is alway a handy thing to have. The Orion ultra block is good. Keep us posted.
That's it;
