[modern][aggro][opinion] New to the Game! Looking for some Help :)

Hey everyone!

I just recently got into the MTG game, and I am super pumped to learn this game I have a bunch of old University friends who play very heavily and have been doing so for many many years.
My husband is also just starting to get back into the game since high school, and we are looking forward to playing with our friends on a weekly game night.

This is my plan. I would like to focus on a Red/Green Aggro deck. This is what I have so far: http://deckbox.org/sets/439659

I have a whole whack of cards I would like to purchase in my wishlist.

I know I have a bunch of different creatures, and I have noticed that most people focus on getting playsets of a few good creatures. I will be moving more towards creating that format once I have enough cards.

Any thoughts of what I should be playing?

Cheers!
