Problem with Comments in Emacs (want them to stop aligning)

This has been driving me nuts for a while.. how in the world do I get the comments to stop aligning to each other? (See the notes in the example code below.) All I want to do is leave one space between the code and the comment, that's all. Maybe my Emacs is screwed up?! Anytime I "Beautify" it does this.

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

entity alu is
    port (A   : in  std_logic_vector(7 downto 0);
	  B   : in  std_logic_vector(7 downto 0);
	  C   : in  std_logic_vector(7 downto 0);
	  D   : in  std_logic_vector(7 downto 0);
	  SEL : in  std_logic_vector(1 downto 0);
	  F   : out std_logic_vector(7 downto 0));
end alu;

architecture rtl of alu is


    -- comment (this is OK)
    process (A, B, SEL)
	variable tempo : std_logic_vector(7 downto 0);
	case SEL is
	    when "00" =>		-- output value of A  (want to leave only ONE space between here)
		F <= A;
	    when "01" =>		-- output value of B (want to leave only ONE space between here)
		F <= B;
	    when "10" =>		-- output value of C (want to leave only ONE space between here)
		F <= C;
	    when "11" =>		-- output value of D (want to leave only ONE space between here)
		F <= D;
	    when others =>		-- output zeros (want to leave only ONE space between here)
		F <= (others => '0');
	end case;
    end process;

end rtl;

Also.. another funny thing, when I decrease the "Inline Comment Column" and "End Line Comment Column". It seems to work BUT... when I go to update my "Sensitivity List Buffer" it places my arguments in the process sensitivity list on separate lines. i.e.
process (A,

I'm using Emacs v23.3 btw

Just noticed its also spacing the crap out of my integer := # constant values. It looks like it's trying to align them to the unsigned values. Anyone know who to fix this as well?

    -- x, y coordinates (0,0) to (639, 479)
    constant MAX_X                                  : integer              := 640;
    constant MAX_Y                                  : integer              := 480;
    -- vertical stripe as a wall
    --- wall left, right boundary
    constant WALL_X_L                               : integer              := 32;
    constant WALL_X_R                               : integer              := 35;
    -- right vertical bar, paddle
    -- bar left, right boundary
    constant BAR_X_L                                : integer              := 600;
    constant BAR_X_R                                : integer              := 603;
    -- bar top, bottom boundary
    signal   i_bar_y_t                              : unsigned(9 downto 0);
    signal   i_bar_y_b                              : unsigned(9 downto 0);
    constant BAR_Y_SIZE                             : integer              := 72;
    -- reg to track top boundary (x position is fixed)
    signal   i_bar_y_t_pos_reg, n_bar_y_t_pos_reg   : unsigned(9 downto 0);
    constant BAR_V                                  : integer              := 4;
    -- square ball
    constant BALL_SIZE                              : integer              := 8;
