Seismic and Radar Dep should be the first two MECH modules you unlock, I think.
Info Gathering is useful, but you'll need time and experience to make the most of them.
Advanced Sensor Range isn't as useful right now, because ECM is just too common. Also, there aren't that many maps where you'll likely have line-of-sight to a mech that far away, that you'd benefit from an increased sensor range.
Advanced Zoom is useful for snipers, but the narrowed field of view really hurts situational awareness. Not what I'd call noob-friendly.
Target Decay is good for LRM boaters, and that's about it. Even then, it's defeated by the Radar Dep.
Hill Climb, Gyros, and a couple others, are pretty much a waste. AT BEST, they're niche AF.
Seismic Sensor, though, passively increases your situational awareness. If an enemy is sneaking up on you from outside your field of view, you'll catch him within a certain range (as long as you're standing still). Good to have that extra Spider-Sense, y'know? Also, can't be spoofed by ECM.
Radar Deprivation means that, even if the enemy has that Target Decay module, when the enemies lose line of sight to you, they lose the red dorito and targeting data IMMEDIATELY. Enemy LRMs got ya down? Well now you can turn it around, sport! Simply equip this wonder module (filled with snake oil, I'm sure), break line of sight, and go on about your business! Money back guarantee! (No, not really.)
Those two modules are PASSIVE, and they're VERY helpful with survivability. Any mech can be helped by having one (or both) aboard. I highly recommend them for the first two new player's mech modules.
My first module was Adv Target decay, before we got all these newfangled wall hack and stealth modules! Anyway, the new ones are waaay better, although Target decay actually counters Radar Dep, not the other way around.
You still get the bonus time from Target decay, just not the normal few seconds. This means that I think you still have a couple seconds of lock on time even if they have Radar Dep and go into cover. It's not ideal for LRM, but it can make a difference still if they think you will lose your lock instantly and wait to go into cover.\
Target Decay can also help out a Streak boat if they are fighting lights with Radar Dep in an urban environment and their target keeps darting between buildings. You'll still have to time your shot perfect though.
Once I bought Radar Dep, my non ECM mechs really jumped in survivability, as well as my light and Medium skirmishers. Not only good against LRM, but the more important minimap of your opponent. Normally, they would have a better idea of your position and heading, but you can duck into cover and then change direction right away to create backstabbing traps and to bug out for another position if flanking or sniping.
Just got the 1st level of Seismic, and Oh man, that is awesome. I'm saving up for the 2nd level right now, but it's super helpful to get an idea of whether there is someone on the other side of that cliff, or which direction they will come out of the rock cover etc.
I made the mistake of getting more weapons modules, but they aren't quite as handy as the Mech modules, unless you are stacking up the Cooldown on an uberquirked mech. Some examples are Dragon 1N, Huginn, Grid Iron, HBK-4J etc. Range is usually a better option, and though I haven't actually bought this one, I wish I had started with something vanilla like ML Range module which can be applied to just about any mech in the IS.
