Reddit reviews Dachshunds For Dummies

Read Dachshunds for Dummies.
Watch kikopup on Youtube for tips on how to train.
Get on your hands & knees and look around for what dangers & attractions puppy will find/destroy, then remove them before he arrives.
Get a dog crate, and teach him that it's the best den a doggo ever had (eg, feed in there, sleep in there, etc).
Learn the Calming Signals that all dogs instinctively use to communicate with body language.
Join rawfeeding yahoo newsgroups to learn how to feed real meat, not kibble crap.
Join a local dachshund meetup group to socialize your dog as often as possible (eg, monthly), so he learns good manners & social behaviors. Take him everywhere, to expose him to your whole world, so he learns to embrace rather than fear it.
Love your puppy. He'll have to be housetrained, which WILL involve mistakes, and takes months to perfect, so please be gentle.
Let your dog be a real dog...which means don't pick him up every few minutes, and do let him sniff & play. Small dog syndrome (then nasty bites later on) comes from being overly protective.
Puppy school at Petsmart was very helpful for us. Ramps are good, stairs are not necessarily evil but best avoided when possible. We put 1 sofa cushion onto the floor so our doxies can climb up & down without danger to backs. We've only had 1 doxie "go down" with IVDD, and Dodgerslist (see RHS of this page) is a most excellent resource. Minis are less susceptible than Standards to back issues, but best to be cautious. Lastly, consider getting a 2nd one after this puppy gets a bit older, cuz they do better with doggie companionship rather than solo. Best wishes for your brand new furbaby. Enjoy him. He's precious. He'll make you happy too.
