just drag and drop onto the Mech in the Mechlab (after removing the stuff you do not want by dragging it off the Mech), above the save button will be a total cost of the changes, including any upgrades and purchase cost for weapons, equipment and modules.
also there are 2 view modes in the Mechlab in the upper left there is a dropdown box for the view mode, you are after "expanded view", as that shows the whole Mech
