In addition to the suggestions already given, Note that there are very few extension tubes available that permit Auto focus and Auto Aperture. The lens you have does not have a manual Aperture setting, so a cheap 'dumb' set of extension tube will not do you much good.
Another choice is a reversing ring and another lens mounted reversed in front of your 50mm. Your Sigma Macro is capable of providing 1:1 magnification, you need greater than that. All of the suggestions will reduce the available light by 1 or more f/stops and as someone has suggested, your DoF will be "thinner than paper" Note the DoF in this photo of a spider that is 2-3 mm
Some other tricks to add to your arsenal:
Spiders - make good macro subjects. Orb weavers like to set there and pose.
For those that don't (Like Jumping Spiders) you can construct an island
with a moat around it. (used for the little girl above)
Cryogenics - 30 minutes in the fridge at 40° F will do wonders to get those little
buggers to slow down long enough for a photo.
And it does not seem to harm them

The key word here is old. Go to a (real) camera store and look at some of the tripods on display. If possible check out the Manfrotto and Gitzo brands too. I'd be guessing but I'll bet the V-3000 cost less than $30. and not much more than that now if one were available. Even the cheaper brands (Sunpak, Velbon, etc) will set up quickly and be more stable than what you now have. Monopods have their place, but they are far from stable. (try walking away from one or take a long exposure photo with one).

You might buy a standalone light meter and go full manual

You might be interested in the TrekPod Go from Trek-Tech http://www.trek-pod.com/
It is a monopod that converts to a tripod. It collapses to fit airline carry-on (if the TSA will let you on board with it). Since the tripod mode uses very short legs, it can present stability issues if not used properly and it is problematic with large lenses, but I find it just the thing for quick field trips where I might want something in the way of support when a handheld shot is not practical.
