The achievements for Velvet Assassin aren't too complicated and won't prove to be much of a problem as long as you follow the guide for all locations of each collectible and take your time. This game can be fast paced at times and much slower at other times so don't rush otherwise you may make mistakes you will regret. Make use of morphine as much as possible and keep an eye on your health as if it doesn't have a blue halo the guards may see you even though you think they can't.
You are going to have to play through the game at least two times as the difficulty achievement do not stack up. Before you read on you need to know that any collectible or secret objective missed you will need to replay the whole game. If you have made it to the end of a level and it hasn't loaded into the next mission you can quit out to the dashboard and load up a previous checkpoint to save yourself if you missed an item.
Step 1: Playthrough #1
On your first run through I recommend picking up all collectibles, completing all secret objectives, kill 300 guards including 200 silently and finish all story related achievements.
The 2 kill achievements are going to be the hardest to obtain as you need to kill so many guards. You don't have to kill every single guard to earn the 300 kill achievement as there are 344 Germans in the game. Some guards are impossible to kill silently but all kills go towards your 300 kill goal. These should both unlock while on the last few levels if you have killed enough guards on your playthrough.
At some points throughout the game you will need to battle a horde of German soldiers before you can either progress or finish off a level. I found that by hiding behind buildings or inside a building you have an advantage to shooting the soldiers as they walk around the corner or through the door. If you're out in the open you won't stand a chance against two or more guards so this technique seems to be the best for these situations if you are having issues.
Morphine also plays a big part in quite a few of the kills you need to do. Using morphine will count towards your silent kills so use it as much as you can. If your going for the detox achievement this can be done on the 3rd level without any problems as you don't really need to use it for any of the kills.
Step 2: Playthrough #2
On your second run through you will be going for the 5 hours achievement and agent difficulty achievement. Also on this run through bypass as many guards as you can, use morphine to bypass sections that you may not want to waste time on. There is no point in picking up collectibles unless they are in front of you as you can add to your health but this doesn't make much difference.
Just to recap what you need to focus on:
+ Kill as many people as you can
+ Complete all secret objectives and find all collectibles
+ Take your time and don't rush
+ Avoid any unwanted confrontations
+ Use morphine as often as you can
+ Move fast but don't rush through the hordes
It is important to take your time and use the maps so you don't miss any collectibles, you are required to play through the game at least 2 times as the difficulty achievements do not stack.
Missing collectibles or secret objectives will require you to replay the whole game, if you miss 1 collectible and haven't finished the level go back for it as you won't be able to replay the mission to pick up items you have missed.
