Power & Cooling:
--[] Heatsink (0.5 tons, size 1) - These will be good for helping with the Sahel contract
--[] Liquid Cooling System (1 ton, size 2, Central only - max 1) - But we want to take this first. It costs 2 HS, and gives us 3.
--[] Power Cell Bank (1.5 tons, size 1) - Range is good, and works with the life support. On the other hand it doesn't help with any of our primary targets.
Computer Systems:
--[] AI Core (0.5 tons, size 0.5, max 1) - Too costly for what it does.
--[] AGILE Drive Controller (0.5 tons, size 1, Front, Rear only - max 1 per location) - Counter productive. Helps one stat for the Amazon contract and hurts the one that will be harder to improve.
--[] ECM Suite (1 ton, size 1, max 1) - EWAR is good, but it's a nice to have not a need.
--[] EPM Suite (1 ton, size 1, max 1)- EWAR is good, but it's a nice to have not a need.
--[] Networked Targeting Computer (0.5 tons, size 0.5, max 1) - This is also good, but it's a nice to have not a need.
Sensors & Comms:
--[] Radar System (0.5 tons, size 0 - externally mounted) - Has it's uses but this thing isn't an air defense unit and it doesn't have the indirect fire mount
--[] Seismic Sensors (1 ton, size 1 - Front, Rear only) - This are fun to use in Battletech but very situational.
--[] Long-Range Comms Array (1 ton, size 0 - externally mounted) - Communications not being jammable is quite nice. I want to try to fit this.
Life Support:
--[] Cockpit Airlock System (1 ton, size 2 - Central only) - This would help for the SCC but our other clients won't care much.
--[] Auto Fire Suppression System (0.5 tons, size 0.5) - This is a steal. I really want one in the central area.
Ammo:
--[] Extra 152mm Ammo (0.5 tons, size 0.5, Central, Rear only) - 25 rounds of ammo is just not enough.
--[] Extra Turret Ammo (0.5 tons, size 0.5, Front only) - Feels less important then main gun ammo.
--[] Extra Drone Ammo (0.5 tons, size 0.5, Rear only) - The drones are a support tool.
--[] Extended Drone Hangar (1.5 tons, size 1, Rear only) - Again, too costly for a light support weapon.
I like the plan by
@CuriousRaptor for the most part. I don't see the point in putting extra drone ammo in, as I feel that recon drones will be more important then a few extra rounds of 40mm for combat drones. This plan gives us 45 rounds of ammo for the main gun. That is still light but I feel that it's the most we can get away with.

You'd need at least 5 tons to get armour worthy of an armoured fighting vehicle, preferably twice that if you want to compete with a high-end enemy tank. This would require some careful planning.
I don't remember where people read "we need 10 tons of armor to compete with tanks", but here's a simple plan to add 4.5 tons of obviously-useful stuff, leave 10 for armor, and call it a day.
It's in the Threadmark.
The thing about fire supression is I'm not quite sure how often it will come into play in this setting. If we're building a mook mecha, we'll see it be outright destroyed more often than hit and damaged. Yes?
Keeping pilots alive and keeping the mech from blowing up means you have a better chance to repair the thing and get it back into the fight. This is a selling feature to people in setting who are not aware of genre tropes.
