everyone is gonna tell you to learn a "real" scripting language, but i 
wont.
yeah, shell scripts are slow and ugly but, after all, it works, and its 
easier than blowing your nose.
anyway i dont have the time to learn perl, so there.

i think it would be easiest to first combine the two files nodeinfo.txt 
and mbtotals.txt into one with three columns, using for example any 
spreadsheet program.
then you can just do something like:
while read LINE
do
NODES=`echo $LINE | awk '{print $1}'`
CUSTOMER=`echo $LINE | awk '{print $2}'`
TOTAL=`echo $LINE | awk '{print $3}'`
echo -e $NODES\t$CUSTOMER\t$TOTAL >> tmpfile
done < nodeinfo.txt

its much easier to work with one file only. otherwise, all i can think 
of is using sed/awk somehow. maybe like:
while read LINE
do
NODES=as above
CUSTOMER=as above
WHAT_LINE_ARE_WE_ON=1
TOTALS=<use awk or sed to print the Nth line of mbtotals.txt, ie the 
$WHAT_LINE_ARE_WE_ONth line>
add one to $WHAT...
echo all to a file >> tmpfile
done < nodeinfo.txt
