Welcome, Kerri! Glad to have you here.

It looks like part of a word got cut off, so I'm guessing here. Not sure if maybe you meant "handle" a shower curtain or "hang" a shower curtain.
As far as how they are hung, all of the similar Chinooks I've seen (Premier, Concourse) have a bendable (pre-bent) aluminum track running around the overhead of the shower, then there are wheeled hooks on the track and a curtain of your choice attaches to that. Normally I see the curtain stowed in the back corner of the toilet in the corner that is adjacent to the kitchen sink area.
As far as how to handle it... I haven't showered in my Chinook, but I'm guessing the curtain might tend to "suck in" on the user. Since the sill is rather low, I think that'd be the spot to watch out for (especially since the outer wall there is MDF, which can soak up water.
It's a bit hard to see in this photo, but if you squint a bit you can see the stock aluminum ceiling track and the stock wheeled hooks. The one change from original in this photo (on the hooks that is) is the small S hooks which are in place of the big shower curtain key shaped hooks. They caused a big gap at the top so were changed. The stock track runs around three sides of the shower (not the sink side). You can click for a larger image (still not the best tho, sorry).

This is another of those "in all the ones I've seen" things, but normally there is a ceiling vent/fan in the overhead of the shower, and it's one with a built in light (around the perimeter). There are two push button switches right on the fan/light - one turns the fan on and off and the other turns the light on and off. The light lenses tend to crack and fall down after a while (likely from UV damage) so it's possibile someone replaced yours with a non-lighted model. If so the wire for the light should (hopefully) still be in the ceiling. Mine comes in from the side over the sink. If you remove the garnish (trim ring) from around the fan you may see it - a pair of red and white wires. There is the ceiling of the shower (white shiny fiberglass) but above that is the regular carpeted ceiling like in the rest of the coach - the wires are between those two ceilings.
You could then either get a new fan-with-light, or (maybe a better option) just use the power for a separate light.
Here is a photo that shows the original fan/light (with the original cracked/yellowed light lens, which I have since changed for a new lens - still not the most robust construction though).

I would always check the anode on any rig new to me. You remove it with a biggish socket (1-1/16" maybe?) and it should like like a fat piece of chalk, maybe the diameter of a garden hose. If it is thinner than that (or worst, just a metal rod is left) then it is spent and you need to screw in a new one. The anode sacrifices itself to save the tank walls of the water heater.
You might want to check about using bleach. It may not be kind to things like the dump valve seals. I haven't sanitized a polyethylene tank since doing it on a boat, but I believe there we used a combination of baking soda and... maybe vinegar? I'm sure other folks here will chime in on this one, and perhaps bleach is fine if it's not too concentrated.
Kerri wrote: Last question: this has a cool beverage mate cup holder, but it doesn't work. Any ideas with that?
Well first thing I'd do is check the fuse. You will see an auxilliary (fairly obviously not Ford) fuse box right in front of your left shin as you sit in the driver's seat. Mine looks like this (see photo). A Premier one will be slightly different. The "missing" 7.5 amp fuse is because I removed the Beverage Mate (I didn't like it at all; just in case you end up feeling the same, any Ford van console from 1997 to 2014 will fit (presuming your 1997 is on a 1997 chassis and not a 1996 chassis).
If the fuse is blown, check the two little side compartments in the beverage mate. They are supposed to be vents and not blocked, but I have seen people put sides on them and use them for storage - could cause overheating.
BTW, if the Beverage Mate is broken and you want one, I believe a few people here have removed them. I was one of them but already sold mine to someone.

PS: Do you have the Chinook manual (blue loose-leaf notebook on mine). If not, I have uploaded at least a 1998 manual in the Reference Documents section. A 1997 will likely be very similar (especially if on a 1997 chassis). There are diagrams for many of the systems - super helpful. See next post for fuse block diagram (limit of three photos per post is why).
