Britt,
I'm not sure what you can take given all of the other meds you are on but you might want to ask about some valium or something similar prior to the procedure because it is clear that you have a lot of anxiety about the procedure (given your last experience). You need to ask about that now so you can get whatever they prescribe and take them ahead of time so they have time to work before you arrive.
Also, tell them to make sure they allow the gel time to work before starting the cysto.
Finally, I'm not an expert but I think the scope is a bit smaller than the catheter so maybe having the catheter before will help you now. That's just my recollection.
Good luck on the procedure! Let us know how it goes.
...and as someone else already mentioned, have someone drive you there and home afterwards.
