what you do mean 'it goes away to the sides'? post a screen shot...
you're probably scrolling up too close and the camera is intersecting with your object... just don't scroll up so close

if i read your second 'problem' right then it's not a problem
when you rotate your object in one view of course it's going to rotate in the other views or the other views are showing you the object incorrectly...

if you rotate an object to see the bottom of it you can just rotate it along the x or z axis 180 degrees (you can do this accurately in the channel box on the right there)

if you want to return it back to its original orientation then assuming you haven't done a freeze transformations after you've rotated it you can just go Modify > Reset Transformations
