There are so many different lures. I am not the trout expert but the most successful one was Mebbs black fury so far. Of course, all depending on the clearness of the water, weather and time of the day. I think they like red dotes.
yes the Mepps Black Fury works really good if you are spin fishing or trolling for trout in a lake. Anything black and gold always works best for me.
If you want to fish with real bait than that's a different story. I think you can use worms or corn as bait. At most places that I fish, bait fishing is prohibited. So I only fish for trout with lures.
O and there are so many colours of lures available because they are supposed to imitate different fish or insects. Trout usually are quiet selective on their diet. Somedays one colour works better that the others. You always try to match the colours to the water you're fishing in and the natural bait that's available in the water. But the black and gold seems to be the colour that works in most cases, so I would just stick with that for the beginning. A second one that is also quiet often successful is red and gold Veltic spinner.
There are two version of powerbait - the powerbait rubber fish and then the powerbait dough. I suppose you mean the dough?
The dough mainly attracts by scent. I haven't used it so far. But if I'd use it I would probably use it on a one or two hook dropper rig. For colours I'd get either yellow, brown or pinkish stuff. Trout might take those colours for corn, trout pellets or trout eggs.
Where are you planning to fish? Is it a stocked lake?
You can get them on eBay in the US. But most tackle store would have them.
The hook is on a wire which goes through the lure. If you use a small snap swivel then you can change colours any time but still use the same hook. This means you don't need a whole bunch of hook guards or special lure bag. You can simply have the lures in you pocket. The coloured part is a lead tube so they are weighted for casting. The fins are a semi-soft plastic so you can bend them to change the action.
If you are going to try worms (I think you call them night crawlers) then use a small bobby float. You want the worm in the top half of the water.
As already pointed out, trout are very much "match the hatch" feeders. They can change their food source literally over night. But worms are a pretty good all-rounder.
