A good place to start is the collection
Galactic North. That has most of the short stories in the Revelation Space universe in chronological order, so that will fill you in on the timeline as you read it.
Here are the stories with the dates they are set:
Revelation Space universeGreat Wall of Mars (2205, published February 2000)
Glacial (2217, published March 2001)
A Spy in Europa (ca. 2330-2340, published 1997)
Weather (2358, published 2006)
The Prefect (2427, published 2007)
Diamond Dogs (ca. 2500 - 2550, published 2001)
Monkey Suit (ca. 2511, published 2009)
Dilation Sleep (ca. 2513-2540, published 1990)
Chasm City (ca. 2517-2524, published 2001)
Grafenwalder's Bestiary (ca. 2540, published 2006)
Turquoise Days (2541, published 2002)
Revelation Space (2524 - 2567, published 2000)
Nightingale (ca. 2600, published 2006)
Redemption Ark (2605 - 2651, published 2002)
Absolution Gap (ca. 2675-3000, published 2003)
Galactic North (ca. 2303-40000, published 1999)
The stories though are stand-alone, they aren't multi-part stories with common protagonists and plotlines continuing through multiple books, but set in a common history.
It's a bit like say Rosemary Sutcliff's British history novels, that range in period from pre-Roman Britain to the 17th C. There are occasional references to characters in other books, but you can read them in any order without worrying about being "spoiled".
There is a great torrent here with several books by Reynolds, multiple version of some books with different narrators.

You don't have to get all 11.5 GB at once. You can just get the parts you want and leave the others for later: go to the file tab of your client.
in uTorrent, first select all files (ctrl-A) and then right-click "Don't download", then select the files you do want and right-click "Priority: normal" and start it. But of course do seed back what you have.
