75k Tune up questions

I have a '04 automatic just about to hit 75 miles on it. right now i am having very minor start up probs that have seem to gotten worse, everything is stock still have replaced much. sometime after its warmed up ill go to say get gas and it wont start back up for 10-15min. and sometimes it takes long turn over to get it to start, maybe 3-5 second. Also the engine has a rough ideal, thinking that a motor mount. i was planning on replacing the ignition wires and spark plugs, also a new moto mount, along with a new starter. Any other idea on thing i should replace? or to help fix the issues im having.



Thanks!!
