Looks like good numbers to me. Should be pretty fun do drive.
I don't know what the Trick Flow kit consists of but with my Trick Flow heads and XE262 Comp Cam and Performer intake I was at 253RWHP and 300RWTQ. Sounds like I am in the same ball park as you.

Art Carr or Hughes 10", 3000 rpm stall. It will flash up to 3600-3800rpms which is right your peak tq comes on. Shift it at 5800-6000 rpms. That converter will keep the rpms above 4000rpms after each shift. Its gonna knock about 5 tenths off your 1/4 et. It will show less rwhp with the stall though. Gotta have one.

The car will still accelerate and take off fine, it will just require a little more throttle and it will feel like the transmission is slipping more down low. Infact it actually is kinda slipping, thats the entire point of a stall speed converter. The taller the gearing(lower numerically) will make the converter even looser. Not sure what gearing you have but if its alteast a 3.36, it will work fine with a 2800-3000 converter. You will need an external tranny cooler to offset the additional heat but driveability and reliablity will be the same. It will definetly suck more gas though. LOL
You could probably go with a Hughes 12", 2500 converter, its very mild and when driving around normal you probably wouldn't notice much difference at all from the stock converter and it would give you a 1000-1500 rpms of flash which will help your launches. I tend to run 3k converters in most of my stuff because the lack of tq in most motors with a good cam, you gotta get em above 3500rpms as quick as possibly if you wanna run a good et.

The chart is kinda screwey to read since the calibration marks on each side don't line up and the "max torque" looks like it labels the torque curve but it's actually riding on the hp line. Still pretty nice power to the rear wheels, though. Anybody have an engine run on the dyno, then compare it to a rear wheel dyno? I'd be interested to see what kind of losses we'd find, particularly as compared to solid rear axle rides.

A 3k stall will be a little loose with a 3.08 but very manageable. It will require more throttle to pull away from stop signs when driving normal in the city but its not like it doesn't move, you just have to give it more throttle. Make no mistake though, a loose converter will DEFINETLY affect your gas mileage, but it all depends on how you drive it. Its really a matter of what you are going to do with the car. I personally would go 3k but I always go a little more then what I need because if you change gears in the future, it will tighten it up, also the bigger stall will make it feel like you have more gear then a 3.08 because it allows the engine to "slip" into the higher rpms easier.
I would suggest either a 2500 or 3000 for you. If you drive it everyday, maybe stick with the 2500.
