No indication that we can see. He's gold starred around 25 songs on expert so far and it looks like you can maybe make one mistake but have to hit every overdrive passage. Example: He'd 5-star a song and get 124k but no gold 5-star. He do it again thinking the score needed was 125k. I can't tell you how many times he'd be 75% or more through a song, miss a note, and start over knowing that he wouldn't gold star it. I'm sure a score list will come out showing the required scores eventually.
And yes, the shorter notes are hammer-ons. As long as you strum the regular sized note before the HOs, you don't have to use the strum bar for the hammer ons/pull offs (just touch the fret buttons).
EDIT: Found this on the scorehero forums. Apparently there's some sort of formula. This is for 360 (couldn't find PS3 yet) but it gives you an idea

The cutoffs will be figured out by 5* cutoffs multiplied by 1.45. Submit either 5* cutoffs or gold star cutoffs to help.
for information on why it's multiplied by 1.45, see PeridotWeapon's post on page 2
In the event that an accurate cutoff isn't known but a close range containing the cutoff is known, the average of the upper and lower bounds will be multiplied by 1.45.
For example, Run to the Hills is between 200,000 and 205,000. The average of these numbers is 202,500. This number will be used as the 5* cutoff in calculations until a more accurate number is produced.
Scores in red are unconfirmed.
Scores in gold are confirmed.
Scores in orange are confirmed to within 100 points.
Numbers in italics are the spread between the lowest gold star score and the highest 5* (non-gold) score.
