Planck team published several sets of of basic cosmic parameters in their report
http://arxiv.org/pdf/1303.5076v1.pdf
see for example Table 5 on page 22.
The rightmost column of Table 5 is labeled "Planck+WP+highL+BAO".
That seems to be the set of numbers that Ned Wright chooses to report, for instance:
ΩΛ = 0.692 ± 0.010
H0 = 67.80 ± 0.77
I'll quote from Wright's "News of the universe" item where he seems to choose that column as most reliable and gives a concise summary of the numbers.

The parameters of the 6-parameter ΛCDM model fit to Planck+WMAP polarization+SPT+ACT+BAO are ΩΛ = 0.692 ± 0.010; the baryon density = 0.416 ± 0.0045 yoctograms per cubic meter; the cold dark matter density = 2.23 ± 0.032 yoctograms per cubic meter; CDM:baryon density ratio = 5.36 ± 0.10; dark energy density = 3352 ± 125 eV/cc; H0 = 67.80 ± 0.77 km/sec/Mpc; and the age of the Universe = 13.798 ± 0.037 Gyr. The baryon density is known to 1.1% precision and the cold dark matter density is known to 1.4% precision.

Other people may have suggestions different from Wright's, which would be interesting to hear.
Suppose we adopt Wright's choice, what Hubbletimes are we looking at? Well the Hubble time is just 1/H. In other words H-1, the reciprocal ("one over") of the Hubble rate. So I put these blue expressions into google calculator:
1/(67.8 km/s per Mpc) and google gives me the present-day H-1 = 14.422 billion years
and
1/(67.8 km/s per Mpc)/0.692^.5 which gives the eventual H-1 = 17.337 billion years
Just for convenience, I'm inclined to round these off to 14.4 and 17.3, provisionally at least, and see how things work.
From Table 2 on page 11, I see that matter radiation equality occurs roughly around 3400.
And the discussion of curvature on page 40 indicates that it's close enough to take as flat for our purposes. The total omega had a central value of 1.001 or 1.0005 depending on which studies' results were combined.
