MustangForums.com - some question but my new project

[hr]ok so i recently bought a 88 mustang gt 5.0. its ben making progress. but i have some questions. it took me about 2 days to get running, i did a oil change, new starter, battery, starterselnoid, fuel filter, intake filter, sparkplugs. its runnen pretty good. for some reson its hard to start when it its not warmed up and running already, it seems like its haven a probelm geten fuel, but once it starts it runs good. takes alot of trys to start. i am thinken the gas had some water from sitting, that that could be it, but im not sure. i put some dry gas in there. well i usaauly unhook my battery when i leave, but this time i didnt and my battery was dead when i went back to it, i jump started it let it run for ahwile to charge, i didnt unhook my cable, and i went back and it was completly dead again. something must be draining my battery but i have no idea what is? my power locks also dont work, what could that be? my drivers side window work, but not my passnger side , i am gguessing its the motor on the passnger side. also what size break lines do 5.0s take, i have acouple leaking. when i bought my car the trunk was latched, i opened it and now it wont lock shut. ive tried wd40 on the latch and stuff, but it stil wont shut. they latches seem really stiff? my heat and stuff when i turn it on, i hear it come on but i dont accauly feel anything blowing out??? i know its alot of question, but i know alot of u guys now most of it. if u could plz help me i would apprecate it. also sory my my bad spelling and grammer lol. here some pics of my car, its maken some progress hopefully will be on the road in a mounth or two. http://i32.photobucket.com/albums/d4...cture001-2.jpg
