Welcome, with the gloves, as far as quality they should work for beginner. They are synthetic which doesnt usually hold up as well as leather but for the price they will do fine. More importantly you want to get wraps. If you jack your wrist up hitting a bag or mitts you could be out for a while.
I would get the title bag gloves(have thumb padding) or mma gloves (open palm no thumb pad)for practice, here is why. If you are getting something for the heavy bag and want thicker padding just get 12-14oz boxing gloves. The extra weight will help speed. You can grapple in safety gloves and bag or training gloves it's just a little awkward.
But if you intend on grappling and striking, I would just get the MMA gloves. When you hit a bag with MMA gloves you might start getting red areas or scuffs on your fingers. This will tell you that you are hitting it wrong.
If you are going to practice with your bro at home I would recommend the Title Incredi-ball focus mitts (comfy and work good) and you 2 can trade off. It takes a while to be a good mitt person. IMO it's harder working mitts than hitting them with combos.
As far as their shorts go I am not too familiar with them. I just ordered a pair of Sprawl v-flex ct shorts, Warrior MMA gloves and wraps, Title ankle supports... I will let you know how everything goes when my order comes in, should be by Mon. or Tue. at latest.
Tapout boardshorts hold up better than their long shorts. Their warmups are great. Shock doctor compression shorts/flexfit cup is great. I hit TJ Maxx for rash guards. This is just some of the gear that I have experience with.
