I'm guessing at some of this, but for sure dry assemble at least once and develop a game plan. People sometimes laugh at my clamp collection, but I can tell you there are times when I've used more than many think are necessary. Beg, borrow, steal what you need. Well, don't steal but you get the picture.
Use slow setting glue, I use Titebond Extend almost exclusively now. No downside that I've found.
There may be a way to do sub-assemblies but I am mostly not in that camp as it can produce surprising and unwanted mis-alignments. Perhaps some of the interior parts can use sides and backs as place holders while saving the glue up of those guide pieces till later.
For me, having a flat, hard and stable surface that's at a comfortable working height is crucial, meaning not the floor. But I'm old. Sawhorses and plywood will suffice, but those rickety fold up tables are almost more hassle than they're worth.
Have everything you need close at hand. You don't want to be searching in your garage or making trips to the store in the middle of a glue-up.
If you can't visualize the process start to finish, I would suggest you're not ready for glue-up. "Figuring it out when I get there" is folly, especially with so many pieces. There's enough to execute without throwing curve balls to yourself.
If you were close, I'd offer to help.
