Tough to say what you'll like, but I'll try this out...
First, on your questions- IPA stands for India Pale Ale. This is usually a pale beer, a touch on the strong side, with more bitterness/hop flavor than your average pale beer. For dark beers that aren't thick and chewy, stick to brown ales, brown porters, or stouts. If you see the world "imperial," expect something syrupy.
In more general terms, let's talk through a few terms.
"Malty" styles can taste like a lot of things... common tastes that come from malts can be cracker, biscuit, bread, caramel, toffee, chocolate, coffee, cereal, etc.
"Hoppy" means a lot of hops. Hops can taste like a bunch of different things. Almost every beer has some hops in it. That can range from just enough to balance out the beer (so you can't taste it) to a ton of hops. Hops add bitterness, but can also add their own flavor. There are a lot of different types of hops out there, but common flavors associated with hops are pine, citrus, resin, flowers, fruits, herb, spice, woodsy. On your next homebrew, when you open the packet of hop pellets, take a big smell of them. That's what you get from hops.
Yeast- often overlooked, yeast plays a huge role in how beer tastes. You can choose a yeast that just ferments and gets out of the way, or you can choose a yeast that adds its own character. Lager yeast or relatively clean American ale yeasts tend to fade into the background, while English ale yeasts can be a bit fruity tasting. Belgian yeasts are something that a lot of people love, but I can't handle them personally. They can be a bit spicy, or taste like a pile of barnyard.
Can you try to describe what kind of beer you'd like to make? Don't think about what's out there, but if you close your eyes, what does the beer you want to make taste like?
