The one I'm putting in is 224/228 .585/.585 114 there are guys running over .600 with more duration on street cars but the ones I have seen have been 6-speed cars. Most people will tell you a 110LSA is a tight to run on an auto but if you remember the police car Z28 from Texas that was in GMHTP (he's a member on here "K9Kev") that car is an auto running a 110LSA. You'll just have to work more on getting the idle issues taken care of.

Im looking for a cam that can make great power, around 385rwhp with my mods, but at the sametime, i am looking for the sound quality of the cam as well. Ive heard cam's that sound mean and have a constant lope sound to them, and ive heard cams that have a mean lope and then theres a slight pause and then again the lope comes back (almost sounds like its about to die). I have an A4 and my most consern is that my car is going to bog and die while at a stop. I believe its becuase of the 110 LSA, correct me if im wrong, thanks

Overlap is what's going to make it sound big and lope. It just so happens that LCA has the biggest impact on overlap. For instance, a 224/224 112 will "lope" more than a 224/224 114 because it has more overlap. It got there by being ground on a tigher lobe seperation angle, but that's really not important. It is overlap that will dictate idle quality or the lack there of that you're going after.
You could have a 114LSA angle cam that sounded way bigger than a 109LSA angle cam. It would require longer duration intake/exhaust lobes on the 114, but it is very possible.

Studytime is right. Overlap is a function of duration and LSA. As an example, a popular camshaft for A4s is the MS3 and it has more overlap than the 232/230 110, despite being on a 113 LSA.
Also, streetablility is not determined solely by the numbers @ 0.050" because numbers at 0.006" (or off the seat) contribute to streetability as well. An aggressive lobed camshaft will have better street manners than a lazier lobe at a given duration @ .050", because the ramp rate is superior. All that means is that a 224 XE lobe is 277 degrees at 0.006" and the same 224 XE-R lobe is only 273 degrees, meaning it will act smaller at idle (more vacuum, etc). An XE-R lobe at 228 will idle the same as a 224 XE lobed cam if the overlap is the same, because the 0.006" duration is the same. By being smaller at such a small lift, the more aggressive lobe can get up to the .050" numbers more quickly (49 degrees on an XE-R intead of 53 degrees on an XE) which translates to better part throttle response.

how much power (HP/TRQ) difference will there between a
232/230 Dur. @.050 .580"/.580" Lift 110 LSA and a
226/226 Dur. @.050 .585"/.585" Lift 112 LSA??

I see you're set on Patriot cams? If it means anything, I just ordered a much bigger cam on a 110LSA for my car. I have an A4 with a 3800 stall/3.73 gears and I just got a 234/242 on a 110.
