I'm an associate professor at the University of Utah. I work on algebraic geometry and commutative algebra.

Reflexive sheaf on normal surfaces
No. Try googling examples of reflexive sheaves.

Is dimension invariant under blowups?
If you blow up the zero ideal, you get the empty scheme. If you blowup an irreducible component, then that component goes away. But yes, outside of that situation everything is fine as the other comments said.

To determine whether an ideal is prime using Macaulay 2
Steven, that's true. You can just check primality over the rationals (or fixed finite extensions) or over finite fields...

To determine whether an ideal is prime using Macaulay 2
Can you define your ideal over the rationals? It appears isPrime does not work over CC (the complexes) but will work over the rationals. Of course, even if you have some algebraic elements that are coefficients of elements, just add them to Q, ie do something like QQ[a,x,y,z]/(a^22) and then you can check whether (x + ay) is prime.

Are universally catenary equidimensional local rings CohenMacaulay?
While I think things like CohenMacaulay and catenaryness (a word?) are probably on topic for mathoverflow, it seems to me that the question is not at a research level. The author should look at standard examples of nonCohenMacaulay rings.

Reference for a lemma on étale maps
There was no editor overseeing a peer review process, however peers certainly do read it and I would hope point out any errors... Perhaps even more frequently than referee's point out errors in published works...
