I'll reiterate what others have said.
- there are cheaper phone options out there (republic wireless, ting, pageplus, freedompop, etc etc etc)
- landscaping/yardwork? Seriously, just DIY it - save money and get some exercise
- beauty & hair - for a guy this is pretty simple: just rough it or DIY it. Even if you're a girl, you could try DIYing it.
- home alarm - I'm pretty sure there are cheaper options out there based on how much monitoring/coverage you need. If you're in a safe area or have neighborhood watch, this probably isn't much of a necessity. You could even DIY/build your own system for relatively cheap (maybe a few hundred bucks startup but DIY email/text alerts) -

- entertainment - what kind of "entertainment" costs you that much per month? Just curious.. is it more so just averaging out vacation/quick getaway costs annually or something?
- cable tv - just stick with OTA, IMHO.
- newspaper/subscriptions - just go to the library or settle with getting your news and stuff online. Or only sign up when there are free subscriptions offered (they exist you just have to look)
- dining - that is quite a lot to be spending eating out. I'm guessing you eat out for lunch at work every day? And probably for dinner too? Learn to cook and bring your own lunch. Even if it's pb&j or pita and hummus... feeling 'hungry' and not needing to eat is actually OK
- 401k - definitely max it out. I made the mistake of not doing this and regret it. Anything that can be considered a tax shelter you should take advantage of and max out to the fullest while you can. Everything else is secondary.
