Well i got some questions about interfaces. Such as i see things like.

24bit/96kHz and 24bit/192kHz. The 192kHz are usually a bit more but is the quality usually a lot better?

I'm looking at things like 828mk3 by MOTU and it seems to be a good price for the things it comes with. But why are things like the MOTU HD192 so much more money when they are both 24bit/192kHz.

Im sorry if these are dumb questions but im just trying to learn as much as a i can about these types of things so i know what im looking for.

better preamps, Analog-Digital converters, most likely better and different types of connections...most of the time more connections.

The MOTU 828s are great units, Tweaks has a review of the mk2 here:

I think this section of his guide goes over the Bit/KHz as well:

Picking an interface can be a challenge but Tweaks guide is a great start and will walk you though just about everything you need to know about recording. This chart should also help you decide on what to look into:
