Hi Joel,
You can use dbreindex live and you don't need to put the database in
single-user mode. Of course you should run this command during off-peak
hours so your users will not get a performance hit.
Hope this helps,

SQL Server Books Online says:
Note Even for an application oriented for many insert and update
operations, the number of database reads typically outnumber database
writes by a factor of 5 to 10. Therefore, specifying a fill factor other
than the default can degrade database read performance by an amount
inversely proportional to the fill factor setting. For example, a fill
factor value of 50 percent can cause database read performance to degrade
by two times.
It is useful to set the fill factor option to another value only when a new
index is created on a table with existing data, and then only when future
changes in that data can be accurately predicted.
Hope this helps,
