United out of Hilo question

[Chunkster]

Taking the UA flight from ITO to LAX tonight and will be checking bags for the first time. I already have my boarding pass and would like to know if there is an express bag drop line for those who checked in on line. If so, where is it? Also, is the little shop inside security still open that late? The last time I did this was way back when it was still a Continental flight. Thanks in advance!
