Yes; whilst being complimentary, they are not identical. The single DNA strand from which mRNA is transcribed, is refered to as the "sense strand". The non coding complimentary strand is called the "anti-sense strand".

Yes, because either side of the DNA strand complements the other. Therefore, the mRNA could theoretically produce two different proteins from the same gene, since it would complement one series of nucleotides or the other, complementary series. (In actuality, it can produce more than two)

Sure it would matter. The strands are complementary, not identical. You'll get different codons on each strand. Suppose you had this DNA molecule:
A=T
T=A
C=G
If the mRNA reads the first strand, you get the codon UAG, which is a stop codon. If it reads the second strand you get AUC, which codes for isoleucine.

Yes, one side is the gene and the other side can be thought of as a combination placeholder and gene protector. The two sides do not say the same thing.
Would it matter if you put your cereal in a bowl or in a plaster cast of the bowl?
