Samsung Admire Cheap Repair?

[Garchomp]

Okay, so I did the thing we all fear most, drop my phone on asphalt and now the screen has a crack in the bottom left of it. I only have $35 and I dont want to pay out of the butt for a new LCD screen glass, but if i have to oh well :/. Also my phone keeps saying it is charging when it is not and turns itself off occasionally. Do I just need to get a new battery for that? It's pretty scuffed up because I was riding a bike when it happened listening to music.
