Those.... don't look like powder funnels. The "drip tip" is the red flag; none of those are going to have particularly wide stems and the long stem is just going to get clogged with powder.

If you're on a budget I'd look for a plastic funnel with a stem OD <24 mm like this one or this one. If you're willing to fork over a little more cash and get a glass one there are nice 24/40 joint funnels like this small one or this huge one.

You don't actually need a dark room, it's a common misconception. You only need that if you plan to use an enlarger and make your own prints. I don't, but only due to lack of space in my apartment - I scan them in and order prints at Costco or Bartells like any normal digital scan.

If you get one of the Paterson Reel tanks like I have in that photo, you just need a changing bag. Put your 1-2 rolls of film, a bottle opener, a pair of scissors, and all the tank pieces in the bag. Seal it up, pop open the film canister with the bottle opener, then spool the film onto the reels. Put both reels back in the tank and seal it up. Everything else can be done in daylight. (you can skip the bag and do this in a pitch black room like your bathroom or a closet if you want. I prefer the bag- I can sit on the couch and watch TV while I spool rolls).

Then you're just dumping in chemicals on a timed schedule and then unspooling and hanging them to dry when complete. B&W is roughly 13 minutes a batch at diluted 1+1, or 6 minutes at stock (full strength) solution. Stock just uses it up twice as fast, but saves time.

B&W = developer (12-15 minutes for most films at 1+1 - check the massive dev chart -> stop bath (1 minute) -> fixer (1 minute) -> rinse (2-3 minutes) -> hang to dry (2ish hours or until totally dry).

Color = developer (6ish minutes) -> blix (2-3 minutes) -> rinse (2-3 minutes) -> stabilizer (1 minute) -> hang to dry (2ish hours).

I'm pulling those numbers from memory, but the unicolor kit has a good guide with it.
