I need to replace the fuse in an HP Designjet 350C. How?

there are a few fuses that are component based I.E. soldered to the circuit rather than a glass shaped fuse, I would recommend that if you have tried a second mains lead that you put a call into a hp representative or HP trained technician to see if its safe to just replace the fuse or if anything more has happened to cause the fuse to trip.
wildly replacing fuses may cause more harm than good.
the right choice is to have a trained tech called out.

When the switch is pushed the indicator lights go on for an instant then turn off.

This is a powre supply problem and could be fatal. They used to be available as a spare but are no longer. The power supply is the same as on the 430/450 and 750 so you may get lucky.

When I print, it slowly shifts so the whole print is skewed. The print head seems to not return quite where it needs to be. What part would I need to replace?

Clean the printer
Clean the drive rollers with alcohol
Check the belt for wear
Clean the rail that the heads ride on
After cleaning, make sure that you calibrate the printer

Driver problem

Also HP makes alot of "universal drivers" that work for tons of printers then you dont have to worry about specific model printers because the universal probably controls it.
