According to Muragen, the subs are Chihiro's with very slight changes.  Polished also used the Chihiro subs.  So the subs might be available from a variety of sources.

The possible advantage to this release isn't the subs but the higher video resolution of the Japanese enhanced DVD version, 1024 x 576p.

Until now, the resolutions available were:
1. R1-DVD: 864 x 480p
2. Yabai DVD: 704 x 480p
3. E-D: 720 x 480p
4. Polished DVD: 880 x 496p

All converted to 16:9 widescreen display from 3:2 original.  But despite Polished slightly higher resolution, I never thought it looked the sharpest or best.  So we'll see if this 576p is a big improvement.

(There is also a Chihiro 720p Widescreen version, but it was an early experiment in upscaling of the censored broadcast.)

There are three levels of censorship available, by the way: All mirror-steam, part steam, no steam.  And 4 original translations.  So good luck finding the combo you're looking for.

And Yabai uses ordered chapters, just for John's benefit.

"download all" eh?

In that case, I should add that not every translation translates all the signs.  Some leave off the ending punchline of ep8, for example.  And the only fansub to actually use the clever credits gag in the OP was Ayako-Subs (oh, the good old days of seeing SpiegelEiXXl's name on a girl's butt or boobs each week).  In fact, they may have created the most fun version of this first season, but they only completed part of the series and good luck finding any of it.

heh, heh, heh.  Now only I have everything.  My precious!
