1) I prefer the 'Best Option' below. The Next option saves a part. If you remove the EMI filter then these options degenerate into the mentioned schematics. 
 
 For best results we parallel 2 caps of different values so the cap Q's overlay providing better combined response. 
 2) You can use adv7611ebz_b_rec.pdf as a reference. 
 Again look at some of the web search for how to layout these caps. 
 I'll be glad to review the schematic and layout when they are ready.)
