The next upgrade for 1500 points is a Castellan or a Styrix. I personally think the Styrix is the best Knight for an AdMech army because it is super cheap in terms of CP. It can be made Krast (take the Krast WLT and relic) and run alone or with some Armiger friends.

At 2000 points, you should scale back Skitarii and bring Guard instead. Especially Catachans. I'd say make 40-60 of them at least with Straken, MiniPriest, and 2x Company Commander, maybe a Platoon Commander for the option. Things are too killy, and Skitarii just aren't durable enough to make a huge difference. You might as well get some bodies to make up for it.

Finally, a unit of 10x Sicaran Infiltrators is great for a Deep Strike option. Or a blob of 20 Corpuscarii; make them Lucius to DS them in.

2. Unless your local meta is all tau/eldar etc. it may be worth having at least one crawler with the neutron laser (again they are under 120pts) as this can really help with heavy vehicles as the guaranteed 3 damage per shot really hurts. don't forget Protector imperative stratagem will add +2 to hit for a crawler as they have data-tethers for free so even a neutron laser can hit a "hard-to-hit" flyer on a 2+.
3. don't mix and match special weapons in a skitarii squad. take 2 plasma calivers/ arc rifles etc. in the squad.
4. a min squad of 5 rangers with 2x Transuranic arquebus & omnispex is about 70 points, they make great backfield objective campers and deep strike denial areas.
5. pick up a couple of enginseers - they are now only 30 points each meaning you can run a battlaion for 165 points minimum (2x enginseers, 3x5 rangers no upgrades). into this battalion you can add special weapons/ substitute vanguard etc. as you are also planning on running TPD & crawlers put them in a spearhead detachment for that additional CP (or another battalion, if you want the additional bodies and CP).
6. Command Points are your friends for AdMech as we have some funky stratagems, which is why you always want to at least run a battalion (I run either two or a brigade at 1500pts or higher).
7. Dragoons with taser are great at scouting, but you need a squad of 3+ to really get them going causing damage (fortunately they are under 70pts per model now, so this is easy to achieve), if you can run them as Stygies as this gives them -2 to hit outside of 12" so both Tau and AdMech opponants will hit on 5+/6+ without any bonuses.
8. best bet will be to probably run as Stygies (as per point 7 above) as this will keep your models alive that much longer in a small game.
