Here's my config that I can explain :) modifier_map entries affect
only applications using the core (old protocol), that includes
Xmonad. key entries affect the whole configuration and allow for easy
remapping.

Probably all you need to disable numlock is
modifier_map none   { <NMLK> }; 

// use right alt exclusively for alt, left alt for meta
// map to *_L keys because xvkbd can emulate only left modifiers
partial modifier_keys
xkb_symbols "ralt_as_mod3" {
	key <RALT> {
		[ Alt_L, Alt_L ]
	};
	modifier_map Mod3 { Alt_L };
	key <LALT> {
		[ Meta_L, Meta_L ]
	};
};

// Switch left control and left shift for healthier Emacsing
xkb_symbols "switch_lctl_lfsh" {
	key <LCTL> {
		[ Shift_L, Shift_L ]
	};
	key <LFSH> {
		[ Control_L, Control_L ]
	};
};

// This is needed to workaround a bug in xvkbd to make
// it use Mode_Switch for AltGr (to choose 2nd group)
partial modifier_keys
xkb_symbols "remove_lvl3_from_mod5" {
	modifier_map none { <LVL3> };
};
