Faded,
I don't actually "Box" with opponents as a sport, but I do practice some boxing methods.
Sorry I don't know any boxing web sites...

I will as my husband and see if he knows any.
IF you don't have a gloves, wrist wrap, and mouth piace yet, those will be nice thing to get. You don't have to get a mouth piace if you are not sparring yet, but eventually it will be something nice to have.
I don't know what equipments boxers use... I wonder if they use "double end bags", I love using it.
And focus mitts, They are awesome tools to have if you have a partner to practice with.
It will be great to have a partner to practice with.
There are some wonderful focus mitts drills boxing drills you can do.
