Oh, man.
The diodes are sound enough.  The OP's just cobbling something together.
Does everything have to meet ├╝ber-stringent design criteria?
If someone was working on something so critical that 2 mV per deg_C really mattered then he wouldn't be asking questions here anyway.
For that matter, I bet that the BT has on-board decoupling.
The diodes, something that everyone needs several of in his indispensable box of stuff, ought to enable the OP to get on with it - a practical means for the present.

Thank you for all the replies! I decided to use a LD1117V33 voltage regulator as described here: http://www.kobakant.at/DIY/?p=563
Hopefully it'll be helpful for somebody else in the future.

Yes I agree but what if he had no clue to begin with... What then?

I guess he has cash to burn and time to wait.
