Stupid question about radiator...

[1hot5.0]

I have kind of a stupid question, but I am still learning about cars. I recently hit tumbleweed on the highway, and ever since, my car has been running about 20 degrees hotter. Im out here this morning cleaning out as much as I can from the radiator. (I'm getting out rocks, parts of the tumbleweed, etc.). There is a bunch of stuff lodged near the top of the radiator and the front of the car that I can not get to due to two hoses in the way. They look as if they screw into little holes, but won't budge.
How can I get these hoses off so I can clear out all of this junk from my radiator?

Also, on a different note, I saw that a bunch of my fins are bent near the top of the radiator. Im thinking maybe it is time to get a new one soon. What do you guys think? What are some good radiators?
