I've filled in the blanks in your table:
1. 2003 UB313 @ 97 AU
Twice as big as Pluto (diameter)
Orbit inclined at 44 degrees
Period 557 years
Very bright object, Magnitude 18.9
Discoverer: Brown
2. 2005 EL61 @ 51 AU
0.70 as big as Pluto (diameter) but ELONGATED
0.32 the mass of Pluto
Orbit inclined at 28 degrees
Period 285 years
Also bright object, Mag 17.5
"seen" in 12" scope by amateurs
within hours of announcement
Has a moon 1% of primary mass in 49-day orbit
Discoverer: Ortiz; Moon discovered by Brown
who had also discovered the primary
but did not announce first
3. 2005 FY9 @ 52 AU
"less than" the diameter of Pluto but not by too much
Orbit inclined at 29 degrees
Period 308 years

Some new info direct from Mike Brown:
o 2003 UB313 is larger then Pluto in diameter, but no larger than twice
Pluto's diameter
o Based on Spitzer measurements 2005 FY9 is confirmed to be smaller than
Pluto
o Attempts to measure 2003 UB313 with Spitzer did not yield any useful
data
o The satellite around 2003 EL61 has a 49-day orbital period
o The surface of 2003 UB313 is similar to Pluto, and it has methane
o They had intended to announce their discoveries in a couple of months,
but their
website was hacked into, which prompted them to announce them today.
