I'm not an expert, but the current values you have indicate you are getting some weird speed, likely "optimized". If you have a solid 3mbps line you should be at something like 3360/860 or something around those numbers (I don't remember the exact values). Your true speed is what you are currently seeing right now, about 2.2/.2 after the overhead.
Most people recommend your values should be at minimum 10db or higher, but strangely your upstream has a lower value. From what I have seen is that most other people the upstream has a higher value than the downstream.
Line Attenuation (dB) 53.1 31.5
Not seeing much wrong here. I believe this indicates you aren't exactly all that close, but should still be able to get 3mbps.
Transmit Power (dBm) 19.8 11.9
This seems okay to me, but I'm not quite sure if it's normal. It seems similar in value to mine, but lower transmit power is better if it can be done.
Have you tried:
1) Powering off and back on the modem to reboot it?
2) If your NID has a test port and if you have a laptop or super long ethernet cable, take it outside to the NID/phone box outside your house and connect the modem to the test port and gather the statistics there to see if you get the same values or better numbers. (Check if you still have a test port before taking the modem outside. I have a dry loop and at some point Verizon removed my test port, which I think boosted my line stats as I originally only got 1.5mbps).
That is what I sometimes do the rare times I see weird values. Sometimes a reboot will cause my modem to resync to better value, but if your line has some issues, it's likely to go back to your lower speed. The NID test will tell you if the wiring in your house is okay if you receive the same values. If you receive better values at the NID, you could have some bad wiring in the house which is not covered by Verizon (home owner responsibility).
As something for you to compare to, my line was getting ~2.5mbps, but strangely enough the automated optimizer decided to bump me up to ~2.9 for some unknown reason after several months of the 2.5 speed. The margin is probably the far edge of stability, but my line is actually rock solid for speed if I run downloads for several hours as a test.
My numbers:

DSL Speed (Kbits/Sec) 3320 860

Line Attenuation (dB) 50.4 30.4
Transmit Power (dBm) 17.7 12.2
In regards to your ping test, the only thing that really tells me is that there was some slowdown around the area of the Verizon-Alter.net routers. Could have been temporary congestion, but is not the root cause of your 2/.2 speed. That problem is due to your modem currently set for those speeds, so maybe try the couple of things above I suggested.
