So under the tree I found a Mission Sniper Lite with the CB Pro package, a RDS system, and a case.

A great choice for sure. I mentioned the Mission 360 only because it has a little more speed. My Mission 400 is a wonderful crossbow. You should really enjoy the Sniper Lite. She did very well by talking to someone that actually knows something about what they sell.

Hopefully they bore sighted it correctly and your time at the gun range will be short. You don't want to shoot too many bullets I mean bolts to get the scope dialed in.

Does someone's bottom still hurt?

I had a first timer archer with me tonight and put a nice doe down. Second deer he has shot with me coaching as he started hunting last season.

Sounds like some bad little boy didn't get what he wanted for Christmas.Well don't worry there's next year.

Now that I have the weapon, what are the expandable head suggestions?

Dar,
 
The Missions have a small cutout at the end of the rail that the broadheads must sit in. At least the MXB 320, 360, and 400 do. Because of that, an expandable with a very compact closed position must be used. I use Swhacker mechanicals in most of my crossbows but they won't fit in the cutout on my Mission without rotating the insert to align the deployment blades so they clear.  
 
If your Sniper Lite is the same way, you have to be sure you mechanicals will clear the side of the cutout. Put an arrow on your rail and slide it all the way back to see where the end of your arrow falls. If it falls within the cutout, that limits your choices. If the arrow extend beyond the cutout, you can shoot pretty much any crossbow mechanical.
 
If the arrow is within the cutout, I suggest NAP Spitfires, the crossbow version. I have used them and many use them out of Missions. They are a great broadhead either way to start with.

So, with all of that being written, what are the recommendations for what I should be purchasing? The research I have done so far has left me overwhelmed with information and confused by what features are important.

I thank those that provide useful responses in advance.

Lot of choices out there for someone just getting into the game. Of these features, what are some that are the most important to you;
 
cost
reliability
customer service
speed
weight
width
ease of cocking
easy maintenance
 

 
 
 
What do you think of the Wicked Ridge line of crossbows by Ten Point? Primarily the Warrior G3

Bought my son a Warrior about 4 years ago.

Shoots and performs just fine but if you have the money for something lighter, more compact and quieter spend it.

It's very front end heavy. Even on the rare occasions I've taken it out by myself without my son, whether in a blind or concealed by natural brush (I don't do treestands) I put it on shooting sticks.

No mechanical issues with it. Factory scope holds its zero just fine. Rage 3 blade mechanicals shoot well out of it.

For what I wanted to spend it's been a good purchase so far in terms of what it's supposed to do but there are definitely cross bows out there that are lighter, more compact, faster and quieter.

Thanks for the info.
 
I wouldn't mind upgrading from my crapping SA Sports Fever.  I still have my older vertical bow, but more and more, I like to stay on the ground when hunting, so xbow fits that bill.

PSU,
The above sums up my thoughts pretty well on the Warrior. I have shot both the Warrior and Invader and recommend both to those looking for lower end, budget bows. Made by Tenpoint so customer service is top notch if you should ever need it and they are both reliable bows.  As long as you are happy with a bow that performs well, but with some tradeoffs, the Wicked Ridge line is nice.
