Your Answer for Question 1:
After a TLB miss occurs, TLB uses a write-back strategy (copying some certain entries back at miss time rather than whenever they are written)that is very efficient, since we expect the TLB miss rate to be small.
The exception for TLB entry missing is much more frequent than L1 cache, the operating system loads the TLB from the page table without examining the entry and restarts the instruction when such an exception occurs.  If the entry is avlid, another exception occurs, and the operating system recognizes that a page fault has occurred.  This method makes the frequent case of a TLB miss FAST, at a slight performance penalty for the infrequent case of a page fault.

Your Answer for Question 2:
I don't think it would because each tag entry in the TLB holds a portion of the virtual page number and each data entry of the TLB holds a physical page number. Thus the order of the bits does matter in this case
