Lucius Malfoy and LV

Ok, first, How did LV get into Slytherine?  I thought you had to be a 
pure blood to get into that house.  Only one of LV's parents was 
magical.  Now, we do know that the Malfoys are pureblood.  I wonder 
what Malfoy may have on LV.  He has a large amount of LV's old school 
things as evidenced in COS.  Not only does he give Ginny the diary 
but he also sells some items and is fearful of the raids by the 
Ministry because of the other items still hidden.  He is helping LV 
by conveniently placing the diary in Ginny's hands.  He (Malfoy) had 
to have heard Harry shout to the death eaters about LV's heritage.  
Will Malfoy (if he did not know about this previously) use this 
information to go against LV to try to be the next Dark Lord?  I 
cannot picture Malfoy in all his pompousness remaining that loyal to 
a muggleborn.  How did he get so many of LV's old items?  Many 
questions......
