Timing belt jobs are kind of scary for some, but if you have the right tools (I stress this), it will make your job so much easier . tbh, even if you do get all good parts (Aisin parts), all the seals, tools and some food/beer, you should still end up with extra money for the other stuff such as valve cover gaskets, fresh (correct) coolant, and misc hoses if you replace them for about the same as charging the shop to do it.
Since your doing the job, I'd recommend all the seals along with the oil pump seal and the O-ring for the oil pump. They sometimes develop a nasty oil leak for the 5SFE.
