Exactly. You don't need anything fancy like CO2 just a standard but good pump like the Topeak Race Rocket HP or the Lezyne Road Drive which ever you can find on sale for the cheapest price.
2 spare tubes is a good idea IF you don't know how to patch a tire, I carry just one tube and only use it if for some reason I can't fix the tube that flatted on the road, so I patch on the road about 98% of the time.
Patches...well the glue on ones are great but they take to long to use and someday you'll be cursing on the side of the road when you discovered that your glue tube dried up! I like Park (Super Patch) and Specialized (Fatboy) brand of glueless patches, they work great and last the life of the tube if done correctly, I've used them for over 20 years with only one failure when I tried a cheap brand once. If you want to know how to use a glueless patch just reply to this post or privately message me.
But you do need to know how to fix a flat on the road if you don't already know how, so learn how to do that before you venture to far from home, learn how to patch too there are a lot of You Tube videos that you watch to get an idea then practice what you watched.
You need to get good quality tire irons, cheap ones can break while trying to mount a tire. Irons like the yellow Pedro's or the Soma steel core ones are the best. Also there is one I use a lot called the QuikStik, this makes taking off and putting on tires very fast, watch a You Tube video on how to use one if you get one of these.
You need a helmet but you don't need a $300 helmet, a good $60 to $80 helmet will suffice and give you better ventilation then the lower costing Walmart jobs and will last longer. Here is a good helmet on closeout:

A multi tool is great if you understand bike mechanics well enough, otherwise it's an option you don't really need right away especially with a new bike. I happen to like the Park MTB3 the best but this is just my opinion, Amazon has them for less than $18 see: .

Some things like a bike computer is not essential unless you want one, and Sigma makes the best computers for the money on the market in my opinion, they make fantastic ones for under $30.
Find as much as you can of the stuff you need on sale or on closeout deals, you save a bundle from just going down to an LBS and loading up on ****.
