Aviation Radio Frequencies, GPS POIs, and Tourist Trains

[JASII]

I recently bought a Garmin StreetPilot 2730 GPS and recently I have been interested in dowloading custom Points Of Interest (POI) files. I am just wondering if anyone here has ran across any aviation specific custom POI files anywhere along the way during their internet surfing. I was sort of thinking that it might be kind of nice to have if they have ever been created. Maybe something in a .csv file that would also tag the aviation radio frequencies. For example:

-93.22810,44.62786
Airlake-KLVN
8140 220th St W
Lakeville, MN
952-469-4040
Clr Del: 118.95/AWOS: 118.0/CTAF: 123.0

I have been playing around with what data to display. The Garmin StreetPilot 2730 will display seven lines of data on the unit itself. Another example is for the following coordinates
-93.03285,44.85713 it displays the following information:

KSGS-FLEMING
CTAF/UNICOM 122.7
WX AWOS-3 119.425
MPLS/STP A/D 121.2
CLEARANCE 118.2
WX ASOS STP 118.35
WX ASOS FCM 124.90

I obtained that information from another website. Do you guys think that the way I have it displayed is okay? Should I have other data? Fleming is an airport without a tower so I think these are the best frequencies.

Here is what Saint Paul Downtown Airport looks like. It is a control tower, but not 24 hours a day:

KSTP-HOLMAN
CTAF 119.100
UNICOM 122.950
ATIS 118.350
GROUND 121.675
MPLS/STP A/D 121.2
CLEARANCE 121.675
