I'm thinking about commenting electronically... which proceeding should I submit my comments under?

Jack Mullaney (one of the committee members and an early proponent of expanding the VHF radio broadcast band down to 76 MHz) recommends you file under MB 07-294, the so-called "diversity docket".
Points I intend to cover in my comments:
1) The proponents have shown that alternative channels are available for full-service TV 5 and 6 stations which had planned to remain on those channels after February 2009. There will be some unforeseen expenses involved for these stations to move to UHF, but many other TV broadcasters have had to deal with this as well. (Remember, Channel 6 stations have been whining about NCE-FM interference for years and reassigned channels will eliminate that problem.)
The remaining question is where to put the Channel 5 and 6 LPTV and translator stations; however, those stations have far greater flexibility to take advantage of directional antennas and terrain shielding, so they can probably make use of "white spaces" in the UHF band that could not accommodate a full-service allocation. Most LPTVs and translators are located in smaller markets which are less congested to begin with.
2) The public interest would be far better served by AM digital operation in the expanded VHF band, rather than continuing with the medium-wave IBOC plan, for the following reasons:
a) Elimination of the digital sideband interference problem in the MW band, particularly at night.
b) All stations, including daytimers, would gain consistent day and night coverage
c) Reception would be much better during storms and near noisy power lines and other sources of RFI
d) "SFN" co-channel boosters could be added to fill in dead spots and improve building penetration in city centers
e) High construction and maintenance costs of multi-tower directional arrays would be eliminated. Keep in mind there was a "baby boom" of new AM stations following WW II -- their towers are now 50-60 years old and many are in need of replacement.
f) IBOC isn't even an option on certain narrowband DAs
g) A shorter wavelength would work better with "compromised" antennas built into cell phones and other portable receivers
3) A reasonable transition period should be set. Most AM broadcasters will not want to give up their medium wave channels until a sufficient number of digital receivers have penetrated the market. The FCC should consider measures to expedite this process.
4) The transition plan should place particular emphasis on public safety benefits as the "quid pro quo" for use of this spectrum, rather than selling it off to the highest bidder.
