The difficulty in reaching 1000 for this game is set in the time consuming nature of one achievement, "Completist". It should take a person 20-40 hours to get 950 and the remaining 30-110 hours grinding out levels on all remaining officers. The game is completed in small non-linear sections and as such there is not really a sense of "playing through" the game apart from working through the achievement list.
Step 1: Unlock All Officers
In no particular order, you should aim to unlock each of the officers as directed by the guide. As you unlock officers, you will get an achievement for each officer as well as credit toward the cumulative achievements. The achievements for Targets and Scenario Completion will unlock as you go. This step will unlock the majority of the game's achievements, but it is no more complicated than unlocking each of the playable characters.
Step 2: Finish Targets
If you have not unlocked the "Target General" achievement, enter "Free Mode" and look at which scenarios have gray diamonds next to their name. You may complete the targets on any difficulty, as any character. You do not have to complete all three targets in a level in one run, you must simply complete each target once and complete the stage with the target completed. If you are having trouble with some targets, do your best to focus on completing just one each time you play a scenario.
Step 3: Complete All Musou Modes
The game does not track which Musou Modes you have previously completed. The easiest way to track it yourself, apart from keeping a list on paper, is to start on a faction and work your way left to right finishing each character's Musou Mode. Alternately, I simply used a different save file for each Musou mode, but you run out of slots near the end. Musou Mode completions do not require you to do anything except complete each scenario in each character's story. Difficulty and Target completion do not factor in.
Step 4: Chaos Mode Completions
Once again, the game does not track what difficulty each scenario has been completed on for you. The simplest way to do this is to choose an appropriate character and work your way down the Free Mode list completing each scenario from top to bottom. For maps with multiple faction scenarios, you must win on all available factions. Attempting to do this achievement in Musou Mode will make it a great deal more difficult.
It is important to have completed steps 1-3 before focusing on this step. Scenarios become available in Free Mode as the previous steps are completed. This is where many people have had difficulty with this achievement, because they tried to do it without all the stages unlocked in Free Mode and/or they lost track of which ones they had completed and subsequently missed some without knowing it.
Chaos Mode can be very difficult for some people, I started a companion thread to my guide that gives more in depth advice on playing through Chaos mode scenarios. It can be found HERE.
Step 5: Challenge Mode
Place first in each of the five mini games in Challenge Mode. The game comes with a pre-set "Top 10" scores in each of the challenges. Their completion is straight forward, but there are some additional tips in the guide if you're having trouble. These may be completed at any time, but the more familiar you are with the game the easier these will be.
Step 6: Completist
At this point you should have 47/48 achievements unlocked. This last achievement is simple in terms of difficulty, but a real test in terms of patience. You must raise each playable officer to level 50. The fastest way to do this is to simply grind out fast, high experience scenarios like the Wei side of Castle He Fei (on two controllers if you can).

The road to 950 is not very long, and even less difficult. Master of Chaos can be challenging, but is very doable with the right character, weapon, and some practice. I would suggest stopping there unless you are one of those people who MUST get 1000 on every game they play ... though if you're that kind of person, I'd suggest skipping this one altogether. The "Completist" achievement alone will take at least three times as long as it took to get the rest of the achievements combined.
