Grum, what you need before flying LHS and wearing the 4 stripes is a recurrent on the left seat.
If your company is serious about it, the will purchase an "upgrade" recurrent on the type, which typically lasts a day or two longer and has more extensive sim training.
Both CAE and FSI offer various ancillary training related to upgrading, such as command CRM seminar. Whether you need these is between you and your ops chief.
Don't forget to check on the requirements for right-hand seat qualification to be done on recurrent, depending on where your aircraft is registered.
Oh, and don't let the mongrels nipping at your heels on this forum get to you..
