I bought 100 rounds of .223.....55 grain I saw some other bullets that were also .223, but they were 45 grain...How does this affect the bullet? i.e. more gun powder = more acc and range??

It is important to remember that the word "grains" refers to weight when it is used to describe modern firearm ammunition. It is an extremely small unit of measurement, with 437.5 grains equaling one ounce. (Or 7,000 grains equals one pound, if you prefer.) This small unit of measurement is used because firearms are precision instruments, and the ammo they use must also be made to extremely close tolerances.
The markings on the boxes of ammo referred to the weight of the bullet alone. For each popular caliber, the ammo manufacturers offer a variety of different bullet weights, bullet shapes, and even what material the bullet is made of. This can be rather confusing at times.
Another source of confusion is the fact that different manufacturers might offer cartridges that use the same type of bullet, but each company usually likes to load different amounts of powder. This means that rounds with different brand names might have the same bullet info on the box, but you will find that they shoot different when you try them out.
Speaking in the broadest possible way, lighter bullets tend to be more accurate at short and medium range because they move faster coming out of the gun and have a flatter trajectory so it is easier to aim precisely. They tend to lose their speed relatively quickly, so they will also hit downrange targets with less force than heavier bullets.
Those heavier bullets are trickier to get precise shots at medium range, but air resistence will effect them less than their lighter brethren. They will retain more speed over longer distances, and so will hit distant targets with greater force.
The first link below will lead to the US Weights and Measures page, which lists all the current units of weights that are standard in America.
The second URL will lead to the Winchester Ammunition page dealing with .223 ammunition. I am linking to Winchester's website not because I am endorsing their products, but simply because they have one of the easiest sites for looking up ballistic data that I have ever come across.

RE:
Is the amount of grain in a bullet referring to the amount of gun powder it has in it?

In this case the grains that you mention are the weight of the bullet. In handloading ammunition, the gunpowder is measured in grains as well as the weight of the bullet.

Your 45gr bullet will travel faster and flatter than the 55gr. Lighter bullets won't guarantee increased accuracy but you will have less adjustment of your shot from close-range to longer distances. Wind will also affect the lighter bullet more. Another consideration is the use; hunting or marksmanship; knockdown power or etc...
Many pro's and con's...

Grain is not gunpowder, it is the weight of the bullet, lighter grain is faster but heaver does more damage and is more accurate.

velocity--speed
I use 157 grain semi wad cutter super .38 special.
makes heck of a hole.same for .357 mag.
.22 and .223 smaller bullet needs less powder (grain) to propel,
