Saints Row is a sandbox style game, which means that you can do almost anything in the city of Stilwater in almost any order. The achievements are also pretty much non-linear, so you don’t have to worry about missing anything. I recommend doing the activities first, as many of them give you weapons or abilities that will make subsequent missions easier, but there really isn’t an order that you have to take these in. The estimated time is a very wide variable, because skill determines much of the estimated time. You can be stuck on a level 8 activity for hours and hours, or you might get it on your first try. Many of the level 8 activities are very difficult, and you have to complete SO many of them for the achievements.
Step 1: Preparation: Hitman/Chop Shop
These are technically part of the activities, but they are very time consuming and will have you running all over Stilwater. A better idea than trying to finish these all at once is to activate them immediately and keep a target (either a car or a hitman victim) on your HUD at all times until you’re done with them. Check a guide for some cars and targets that only appear at certain points in the game, and don’t leave them on your HUD, hoping they’ll randomly show up.
Step 2: Activities - 13 
The best way to grind through the activities is to take on one at a time and hit up each location until you get the achievement for that activity. There are three locations on each section of the map (except for snatch which has four), so just make sure you get them all. You can check the status of your activity progress at anytime in the main menu. I included "Grifter" and "Getting Up" in these as well, although they aren’t the standard activity achievements.
Step 3: Story - 6 
As soon as you join the Saints you can start on these missions. I like to finish one gang off completely before starting the next one, but again, the game will not hold you to any specific order.
Step 4: Random - 12 
These are the achievements that the game won’t prompt you to complete with icons on the map. They include "Penny Pincher", "Shopaholic", "Grease Monkey", "Leader of the Pack", "Audiophile", "Jumped the Shark", "Professional Thief", "Scourge of the Air", "Stilwater PD Award", "Addicted to tha Row", "Marathon Runner", "Negotiator", and "Tourist". Some Homies aren’t available for the Leader of the Pack achievement until certain missions or activities are complete, but all the others can be done at any time.
Step 5: Online - 12 
You have a different character for online achievements, so no bonuses that you get in single player will carry over. I recommend boosting these, using the achievement trading thread in the forums. Getting these legitimately takes a ridiculous level of skill and could take up to or more than 100 hours. It also requires teammates who are willing to let you get the achievement pieces, which is very rare.
