It's okay just where it is.
Sorry for the lack of a response.
I try not to answer all the questions that come by, gives others a chance to help out and gets folks involved.
Well it all depends on what was existing.
Did you have water while the plastic was there before you fixed the outside?
Do you have water now after your drains have been put in?
Sealing the foundation from the inside is usually a waste of time and money. The water comes in from the exterior, from the walls, floors and cracks and seams, this you already know I am sure. Sounds like you want to try to stop the migration of vapor, this is tough to control at best.
What this means are there is no guarantee what you want to do will work.
Seal the basement walls,plastic is easier to control if there is spalling of the walls or issues in the future. And water can be controlled to drain to a wall drain if this becomes an issue, and you do not have to do it again in 10 years.
Thoroseal can cause water to get trapped and spall(deteriorate) the block if there is too much moisture.
Hope this helps, try to remember fiberglass against a basement wall can support mold. Fiberglass traps air to create the insulation barrier. Styro or dow blueboard does not. Insulate as a continuous sheet then build your walls.
I have applied a few steel studs across the concrete and screwed the sheets to it. Then built a wall.
Hopefully otheres will direct you to a site or two. Search basement finishing to get advice.
