If you already know calculus, and you have finished Giancoli's calculus-based text, then you have several options. You should look at the websites of the physics departments of colleges you are interested in, and see what texts they use for second year students, but popular texts for the next level up in mechanics are Kleppner or John Taylor, and for E&M is Purcell (Berkeley Course Vol 2).
Giancoli is mostly a crappy plug-in book that teaches formulas rather than concepts, so I guess now the healing can begin :-)
Kleppner and Purcell are very good books for students who have extremely strong mathematical preparation, but it sounds like Nobelium doesn't know calculus, so I think that's a bad match.
Nobelium, if you're interested in learning some relativity, some books I like are (from easiest to hardest):
Takeuchi, An Illustrated Guide to Relativity
Mermin, It's About Time: Understanding Einstein's Relativity
Taylor and Wheeler, Spacetime Physics
The nice thing about relativity is that it can be understood with a minimum of math. Takeuchi and Mermin barely even use basic algebra.
If you can learn some calculus, you will have a much larger selection of higher-quality physics books you can use. Rather than wading through a 1000-page doorstop of a calc book, I'd recommend Calculus Made Easy by Silvanus Thompson.
