I have a Pearl Session Maple kit as well. I have had them for about 6 years.
My tom sizes are 8x8, 10x8, 12x10, 14x12 & 22x18.
I use a Yamaha Steve Jordan snare drum.
Honestly, I think this is one of the best sounding kit's I've ever heard for the price. I'm 22 now but I began drumming in 1999 when I was just 10. It was a christmas gift from my parents after playing on a Pearl export kit for 6 yrs. I got the 5 piece shells for about $1249.99 and added the 8" tom for another, let's say, $150 "ish".
I, NOW, work @ Guitar Center & I have met a bunch of people with the exception of a handful that love Pearl Drums and do not down talk Pearl. I enjoy playing Pearl and I love the mounting systems, hardware, shells etc. (even though I wish they made the sessions with virgin kicks). I also prefer the 7/8 tubing way more than the PDP, DW, Tama, Gretsch, OCDP mounts. To me the pearl is extremely sturdy.
As far as heads go... I personally prefer coated heads but I have used pinstripes, ambassadors, emperors and I currently have the black suedes on there which are great but I havent had the chance to replace them.
I would definitely recommend coated ambassadors. I have the Benny Greb DVD & I will try using coated ambassadors on the bottom, as he recommends, being that I've never experimented with coated heads on the bottom. It should give it a slightly warmer sound. It all depends on what style of music you play but I love the resonance and musicality/tone of coated heads since clear heads feel like a "thump" to me personally.
I hope you enjoy your kit. It's an awesome set. Don't worry too much about heads, just tune them right and you'll be amazed how well they sound.
