Batman: Mad Love is a good read that goes into her origin.
From there you could read her 2000-2004 comic. There's also Batman: Harley Quinn which has several different stories featuring the character.
Can't comment on the Sucide Squad stuff since I haven't read much of it yet.
The Palmiotti & Conner ongoing is a good comic to read if you if you like seeing her in more comedic and silly stories.
There's also lots of specials. The Valentines Day special is hilarious, the Christmas one has its moments but is kind of meh, The Road Trip one is amusing and fanservicy.
Lastly, Harley's Little Black Book is a bimonthly comic that features team ups between Harley and DCU characters. Whether or not you'll like this is probably dependent on how much you like the current comics and specials.
