My first thought is be careful you don't introduce diseases and/or parasites. Sourcing that many wild forage fish, you're bound to get a few that are diseased or carrying parasites. There are steps you can take to minimize that risk though...
You can stock adult LMB, but again be sure you are sourcing healthy fish if you are obtaining them from the wild. I would keep the bass in the 8"-12" range, but I'd wouldn't stock bass any larger than 14". I would stock about 30 bass in that size range. That should get you off to a good start. I would get the redear sunfish(RES) in as soon as possible or stock larger fingerlings so that they are not eaten by the larger bass you will be stocking.
Most species of crawdads found in streams are not adapted to pond life and will either die or leave the pond to find a suitable habitat. You may want to spend your time trapping and or netting crawdads from a local lake or pond to make sure you are getting species that are adapted to pond life.
Do you know what species of chub, shiner and sucker you are collecting? Some species may be worth collecting and stocking in your pond prior to the introduction or bass next year in the hopes that they take hold, spawn and build numbers prior to the bass introduction. If you are unsure of the species, take photos and post them and we'll help ID them for you...
You mention having stocked HBG but not pure BG. HBG have very limited reproductive capability which means they will not be able to support a healthy bass fishery. Is there a reason you are not stocking pure BG? They have the reproductive capacity to support a healthy bass fishery. I know you plan to seine large numbers of forage fish, but seining can be a lot of work and having to do it on a regular basis could get very old after a year or two...
