Novice here with questions

We Just moved into a townhome. The top floor has hardwood floors, three very large windows (4' x 6') and a slanted ceiling that at its highest point is 16 feet. Because of all the glass and the sloped ceiling the acoustics are what I would consider weird. The room dimensions are 27' long by 16' across, and there is no way to add ceiling speakers or any speakers in the rear. My budget for a receiver, cd player, and two speakers is $2000. I am aware the options are limitless, but would like your opinion on what percentage to spend on receiver vs speakers to get the most bang for my $, as well as what kind or type of speaker might best handle this room.
