No. Register accesses etc are exactly the same for accessing the 
standard registers r0..r15 and accessing peripherals etc.

Thumb mode is just a "compressed" form of an ARM instruction. That is, 
every Thumb instruction decodes into an effective ARM instruction., 
Some ARM instructions do not have THumb equivalents.

You will still need to write some ARM code and tie them together (ie. 
interworking).
