Answer 1

How about:

find /path/you/need -type f -exec md5sum {} \; > checksums.md5

Update#1: Improved the command based on @twalberg's recommendation to handle white spaces in file names.

Update#2: Improved based on @jil's suggestion, to remove unnecessary xargs call and use -exec option of find instead.

Update#3: @Blake a naive implementation of your script would look something like this:

#!/bin/bash
# Usage: checksumchecker.sh 
find "$1" -type f -exec md5sum {} \; > "$1"__checksums.md5
