If you meter Ilford Delta 3200 at EI 1000, you could ask the lab for "pull processing." But many photographers expose their B&W negative film at one-half of the box speed and then process it normally. Suggest you ask the lab for their advice -- they may or may not offer pull-processing (and if they do, they may charge extra).
There are several factors that are going to affect the outcome, such as your metering technique, what you plan to do with the negatives (scan vs. wet print), etc. But if you meter Ilford Delta 3200 at EI 1000 and have it processed normally, I think there is a good chance your negatives will be acceptable. However, without reducing the normal processing time (known as pull processing), there is a chance your negatives may be a little bit dense and contrasty. You won't know for sure if that is acceptable until you try it.
As for metering, the simple thing to do would be to load the Canon A1 with Ilford Delta 3200 and set the ASA dial to 3200. ;-)
But if you want to use the point-and-shoot set to ASA 1000, that will probably work, too. For "evening light" I don't anticipate problems metering with any of the cameras you list; but when you say, "dark" -- then meter sensitivity may become an issue? For example, the Canon A1 has a silicon meter cell which can read down to EV -2. There are several different versions of the Canon AF35m, but autoexposure on those may only work down to EV 4 or EV 6. Many older cameras use CdS meter cells (Cadmiun sulfide) which are usually not as sensitive in very low light compared to the newer silicon cells.
One solution would be to forget about trying to meter and use a chart to choose a recommended exposure for the kind of light you are shooting under. For example, there are charts like this one from Fred Parker's "ULTIMATE EXPOSURE COMPUTER" that show:
... continues. To use the chart, you need another chart that shows which combinations of shutter speed and aperture should be used for a given EV at a given ISO.
