Random points here:
Liquid bandage is not a wound closure, it is a dressing. It will not work to close a wound so don't plan on using it as such. For the weight of the bottle you can carry more dressings.
Superglue works, but is exothermic- it gives off heat as it cures, which can damage surrounding tissue. Do not use it for sensitive areas. Dermabond (and similar solutions) is designed for wound closure; as such it is formulated slightly different and is not as exothermic. It is not appropriate for use on all wounds and can make a bad situation worse.

If you don't know how to suture, LEARN beforehand.
You can do a LOT more damage by improperly closing a wound than by leaving it open. There are plenty of manuals out on suturing- read them and actually practice it. You need several things in addition to the needle and thread to suture; instead of telling you, I’ll just say read up on suturing. If you don’t learn, don’t suture!
2% Lidocaine is generally used in dental work- 1% and 1% with epinephrine are usually used in wound closure (depends on the region of the body). Do not use Lido w/ epi on ears, nose, fingers, toes or genitals. Some people have sensitivities to Lidocaine. As badly as lidocaine burns, if you only need a couple of sutures you may be able to close the wound faster and easier w/o it.
Staples are much easier to put in, especially in yourself. They don't look as pretty as sutures, but they work very well for some applications. You don't need lidocaine with them, pop and go usually works just fine. Again, if you don't know how to or which wounds need closing and which don't and how to properly prepare a wound for closure- don't close it. Wounds left open will granulate in on their own, they'll just be ugly (there are ways of dressing these to reduce scarring).
Steristrips work very well for small lacerations and don't tend to scar as badly as sutures in some applications. Have some benzoin tincture ampules with them for increased adhesion.
The point I’m trying to make in the above is that there are other ways to close a wound and that there are many other factors than just- wow! Laceration, sew it shut. Even after you get it shut you need to know proper wound care.
What do you plan to do with the syringes? If you don't have any injectable medications they aren't good for much else and may run you afoul of the law if you ever get searched. A curved tip syringe or irrigation syringe is a better choice (for wound cleaning).
Keep your pills in the original packaging if at all possible. Blister packs are great for this. Again, trying to explain to the cop on the side of the road what your various colored pills are is not going to go well; none that I know carry a PDR with them.
What “assorted creams” do you need? Triple antibiotic and burn gel (OTC) /silvadene (prescription- know where and when to use it) will cover most any problem. Some betadine solution/ointment is nice too (another multiuse item).
Drop the blood tubes. If you don’t have a lab with you they’re worthless.
What do you plan to do with the plaster bandage? Do you know how to set a bone? It usually takes more than one in most cases anyways. They are heavy and generally bulky. Add a Sam splint, a finger splint (commonly broken bones) and the knowledge of how to improvise.
Add an ACE bandage. Multiuse item that works for pressure dressings too.
Make sure you put your supplies in ziplocks or something else waterproof. Water soaks right through the paper wraps on dressings. Vacuum packing bulky items works well.
Know what allergies you and anyone in your party might have. There are an increasing number of people who are allergic to latex and some types of medical tape for example.
These are all just basic suggestions. Remember, EMT class prepares you for basic package and transport, it does not teach you anything advanced or any long term care. It’s a great start, and I’d definitely suggest wilderness EMT also, but anything out of your scope of practice you will most likely have to learn on your own. Fortunately there are many good books on the subject and it’s not an impossibility by any stretch.
