Not sure what classes are offered on DAW use - I know Guitar Center has (or used to have) a very basic Pro Tools class - really just a teaser to get people to buy PT.
The best way to learn to use a DAW is to do it, and keep doing it (really no different than learning anything else - practice practice practice).
the forums at homerecording.com offer lots of advice and answers to questions you may have. There is an 'MP3 Clinic' where people post their recordings and get others to listen and comment on things that can be improved (the more you participate, the more you get help).

Not sure what Neumann mic you are looking at, but if your recording space is not optimal, you may be putting more money into the mic than is really necessary. I think the least expensive Neuman is about $700. You are unlikely to hear any difference in your recordings using that mic compared to something in the <$300 range. What a sensitive condenser mic WILL pick up is any untamed room reflections and noise in the tracking space.
Most home recordists treat their spaces with sound-absorbing materials (rockwool or compressed fiberglass, not 'acoustic foam', which doesn't do anything for the low-mid and bass frequencies), ideally making the rooms somewhat 'dead' - and then adding reverb back into the recording during mixing. Unless you have concert-hall acoustics in your home's recording room, this is usually the best bet.
The last thing to consider is how you are listening to your recordings. Headphones can give you a false stereo image and until you spend several hundreds of dollars on a set, a non-flat frequency spectrum. Also, the nearness of the transducers to your ears can have an effect.
So using near-field monitors in your mixing/recording space is required. Homerecording can be a definite rabbit-hole of 'more more more equipment'!
