Confused about wiring up my ESP8266-01

Hi,
First please forgive me if I am about to ask something silly; I am new to the world of the ESP
I've been reading around here and countless other sites for a couple of weeks now trying to find the "correct" way to wire up my ESP8266-01. In particular the "correct" way to deal with CH_PD and RST.
There are sources which say these can be connected directly to 3.3v, there are sources that say they must be connected through a resistor but give no values, there are sources which quote values of 1k, 3k3 or 10k. There are also resources which suggest to leave RST floating rather than tieing it high at all (as it apparently has it's own internal pull-up).
I know these modules are cheap, but the project I am planning requires long periods of unattended reliable operation and I want to get the design right first time.
Even Kolban's wonderful e-book shows examples of both direct connection and connection via a resistor with no notes as to the relative merits of each method.
Is there a "correct" way of doing this, or does it really not matter?
