You can, however there is still plenty of work to be done with the bound
11,000,000, and you are somewhat more likely to find a factor using that
bound (that said, F(14) is quite possibly the least likely number to be
factored in the forseeable future of any that GIMPS is now working on).

No, that's not a concern - Prime95, and the other 'official' GIMPS clients,
use a random-number generator to determine which curves to test. I don't
know the exact periodicity of the generator being used, but I'm sure it's
high enough that the CPU time lost due to duplicate curves is a very minor
concern.

No problem.
