    I've dealt with integrals with infinity before. When considering the part x >= 1 , do I take the limit as if it's a very large number? i.e. ## \int_0^{\infty} x^{-2.5} \ dx = 2/3 ## ?

    Yes, take the limit as the upper value goes to infinity.

    You mean ##\int_1^\infty##. What you have written would diverge.
