It may not seem like it at first, but you get plenty of modules to spend on your skills. You are right before the cyber module income ramps up. Don't overthink this.. you will be fine.

A great beginner build (and one i am using) is something I saw on a steam guide. It centers around being a Navy specialist. Basically it goes like this:

Attributes

Strength - should be close to max, due to the extra inventory space and weapons. Implants can help out with this.

Endurance - Since you are playing on easy you don't need to level this up past 2. Hypos can counteract.

Agility - useless

Psionics - not applicable to this build

Cyber Affinity - Very important. Decreases difficulty of hacking, repairing, and modifying. The primary use that this build
gets from it is the decreased difficulty in hacking.

Combat

Standard - Should be the highest combat skill. Max it out. Pistols, Shotguns, and Assault Rifles have a lot of ammo laying around. Energy and Heavy weapons should at least have 1 skill point in them. I brought my standard weapons up to 4 then put 1 in energy and heavy.

Hacking - should be the highest tech skill. It always comes in handy!

Maintenance - should be up there as well (I left it at 4). If you have a sufficient maintenance skill, then you won't ever
need to repair your weapons. Don't worry, you will have ample opportunity to acquire maintenance tools.
If you really need to repair something, then you can use an auto-repair unit.

Modify - Weapons can be modified to level 2 (from a base level of 0). I put no points into these. Why? Because you run
into items that can modify your weapons. They are called French-Epstein devices. There can be a benefit to
having thie skill, but I have been doing just fine without it.

Research - You should have at least 1 to 2 points in research for the combat bonuses and info you receive from
performing research. I brought mine up to 4, but the guide said to just leave it at 1. The reason why I
brought my research skill up was to reduce the amount of time it took to research an item. There are some
items/enemies that require you to have a set level of research. 1 or 2 points should get you through just
fine.

Psionics are optional, but the game seems to encourage specializing, which is why this build doesn't use it. However, the guide did say that you could take Psychogenic Cyber-Affinity as an option. It's useful when hacking and it doesn't matter that the boost is limited to two minutes, because you normally hack in safe moments only.

O/S Upgrades

A total of four of these can be found throughout the game. You get to choose from 16. I recommend going with the following:

Sharpshooter - +15% damage to all ranged, non-psionic weapons.

Cybernetically Enhanced - +1 implant slot

Replicator Expert - -20% discount on all replicator items

Pharmo-Friendly - +20% benefit from all hypos.

Implants

Useful implants are BrawnBoost, ExperTech, LabAssistant (when researching), and the WormMind implants.

Hopefully that helps you out. Don't be stingy with your implants, there are plenty of opportunities to hit up recharge stations. Oh and don't be like me and forget halfway through the game that you have to manually drag and drop the surgical unit keys onto the unit itself!
