shift points is NOT the big deal people make if it because the pcm gets it's info from the tailshaft housing which is before the gears affect things. The speedo will obviously be way off.
Ask questions first, THEN buy parts, your distributor is more likely to give you trouble than a stock one and gears are more about feel than actual 0-60mph improvement. They will make it feel like a whole new car but as said for real measurable improvement a converter would have been better and should have been done with the tranny. Most reputable 4L60E builders actually prefer a 9.5" performance piece vs a stock converter, and there are a few tweaks made in the tranny for a high stall converter.

If you buy another converter you are going to want a 9.5" which come in 2800+ stall speeds, usually more like 3200+.
Edge Racing is about as inexpensive as I would go and they are about $550.
The hard shifts down low and softer up high sounds to me like the shift kit was not setup right which is common since few shops are actually capable of building a performance 4L60E.
Far as the tune you need a professional custom tune, someone like pcmperformance or Ion Soltan of Madz28 or a whole bunch of others can do it. If you tell us where you are maybe we know of someone close.

DUDE, REVMAX converter. Check them out, they are a sponsor now I believe. They will custom build every single piece of the converter to your choosing so you don't end up paying for things you don't need. I have owned yank, bmr, edge, and REVMAX most recently. Yank is hands down the best but very pricey. Bmr was junk. Edge was a very nice piece and I had no complaints. But the REVMAX in my 383 car is outstanding for the 300$ shipped I believe I payed for it (sponsor sale). I bought a few upgrades and basically got a converter good to 450-500 hp for a mostly street driven and highly abused vehicle lol. It's been excellent. Cars a forged 383 with a older-school cc306 cam, stall is a 3600 with a carbon fiber lockup clutch and like I said a few other upgrades. Flashes right up to 3600 when you stomp it, but requires no extra peddle to get moving from a stop.
That's just my .02 cents, there are tons of great converters out there but after this one ill never buy from another company again.
PS for an auto car 373s are generally the gear of choice, depending on your plans for the car. 410s will be great, and fun, but if you start making some decent power those tires are gonna be spinning like crazy, and you'll be revving pretty high on the hwy. stuff like that doesn't bother me in the least, but its something to think about if it matters to you.
I fell back in love with my M6 after the 410s and new clutch... Mgw shifter was awesome too... Love these damn cars

4.10s aren't that bad with an A4 car, those who say things like, aren't quite capable of comprehending OD and lockup.
Yes 4.10s can be a bit more gear than some are comfortable with on LONG trips on the highway, but the rpm isn't that bad, think about it this way, with the lockup we are still better off with 4.10s in drive than a old musclecar was with the same rear gear because they always had converter slip, then we have OD on top of lockup.
are going to make that engine scream at highway speed's

I've had 4:10's, 3:73's, and 3:23's....
The 4:10's were fun but really just to blow the tires off. I also like to get on the highway; so the rpms with these put cruising above 70 a little irritating. Fun but in this economy not so much.
The 3:73's are just about right. With them i actually feel like i have a 1st gear. they do seem that they still are not utilizing the torque of the motor properly.
The 3:23's were fine for cruising about everywhere except for in town driving. not enough gear for fun light to light driving.
3:42's are what i will be putting in the car next. I believe with the stall and these gears the car will use every bit of torque to it advantage but not be so long legged that it stays in the same gear too long.
