Your problem isn't where you think it is. Your backquoted command is working just as you expect it to, but when you echo $tb you are expanding the contents of $tb and then passing them to echo. Since the contents of the variable contains asterisks, they are expanded on the echo command line, not as a part of the sed pipeline. Try this:

Code:
tb=`echo "Select Date" | sed 's! !&\/\* bm=001 run=000001 \*\/ !'`; echo "$tb"

You should be able to step back and insert the variables.

And your perception of how back quoting works is just fine. If you are using Kshell or bash, $(command) is the preferred usage; back ticks are deprecated in Kshell (and I assume in bash, but I don't know that for fact).
