Yes on both counts. I've written a Q&A style tutorial about coax that 
addresses these issues, and a lot more.

Another point -- some of us DO have long runs to our antennas, so losses 
can be significant. I have two runs to TX antennas that are 350 ft and 
two for 160M that are 280 ft.  My neighbor, K6XX, has some runs that are 
nearly 1,000 ft, for which he's using parallel runs of hard line.
