Pretty much on target here in my signature there is a link with a wealth of info which even though you have some good info so far will make informative reading with links for additional articles wich should help a lot!!!
Hang in there, you have a new part time job which is water changing!!! But it will go to maintanence mode before you know it.
My most useful tip other than using Prime a (and testing your tap water periodically to see how much of any it change, a call to the water provider department and see if they always get their water from the same source or change it periodically, Like from a mud lake or a rock reservoir) is NEVER wash your filter pads/media with tap water as the chlorine and Chloramine will kill your BB, and do not change them to new ones unless it was falling apart.
If you have a HOB - hang on the back of tank filter, you probably have room for a second filter pad which will help with building the colony as large as possible (more surface area to grow more BB)
You can swish the filter in the bucket of pwc water. My recommendation also is to do cleaning on a rotating basis. Weekly ~25% pwc, then, one week clean filter pad, one week clean the glass if needed (I almost never need to do this one and leave it for the algae eaters so skip it), one week no extra cleaning, one week clean substate/vacuum, one week extra large pwc.
The reason is to not clean every surface and destroy too much BB at one time. So if you over feed and need to vac more often, (reduce feeding lol), you can change the maintenance schedule to what works for you (say needed larger weekly pwc for example).
Also how long is your tank light on each day? What is your light bulb or fixture? Is there a number with a K after it, a Kelvin or K rating? Example 5600K.
Some people find using a timer to be ideal, and a split photo (lights on) period. Morning for 4 hours and then when you all get home from work and want to watch the tank another 5-8 hours depending one algae issues.
Hoping you get to love your tank and enjoy it soon!!!
