First, welcome. Secondly, realize that the instructinos that come with most brewing kits are based off of dated information. You will see some argument about it but generally now, secondary is only necessary for prolonged ageing of complex high abv beers, and fruiting/oaking/souring/etc. I have kept beer in the primary and on the yeast cake for 4 months with no off flavors generated. So, in my opinion, go ahead and skip secondary for most beers unless you need the fermenter for your next brew.
Also, keep in mind that the ferment X days then package mentality is flawed as yeast can be fickle and work at different rates depending on temperature, age and pitch rates. Ferment until you get the same gravity over three days then package.
