96 Ram 1500 Electrical 7 Vac. Problems

First, there is a problem when I try to start my truck. It will click for a little bit like the batteries dead, but then all the sudden it starts fine. Sometimes it will die, because it is flooded from turning over so much.

Second, I just started my truck this afternoon and now it Idles around 2200. It's sounds like a vac. leak. I tried looking quickly, because I had to get to work, but didn't even see any vac. lines. When driving I can hear a faint wistle, like a vac. leak sounds like, but when I give it alot of gas it goes away. I never really noticed if this sound was there before, but I dont think it was.

passenger side near the throttle body look for vacuum lines. it controls your heater and ac doors
