"but I am going to refinish the stand this summer to match my home a little better. "
You might not want to tear down the tank once you get it running if you start the build now.
If you do start running the now, you could run it as a fish only tank while you gather your build supplies and get comfortable with the hobby. If you do go that way, you'll need a food source for the bacteria culture in you canister filter. The simplest thing would be a fish. With 90 ga to work with and some self control e. only put one fish in. to cycle and revitalize the biofilter.
You could then leave the tank bare until summer when you'll want to refinish the tank. Now, take the time to research/read this site's old threads. Start to develop a plan on what will work well in that tank within your budget.
If I were in that situation, I would slowly collect my fish and let them grow out in the tank for the mean time. Them after I refinish the stand would build my aquascape.
Read the Substrate, Lighting, and Plant sub-forums. Look at plants that tend to grow tall. Don't fall in love with carpet plants they'll break you heart in a tank like this.
Great tank for Madagascar Lace, Jungle Val, Cryptocoryne Affinis, Echinodorus "Rubin" and so many other larger plants. Java fern can be grown on driftwood getting higher up in the tank to get more light.
The best tanks typically are a result of the best planning.

>if you are very far North in Canada, you should have access to pristine streams, you could collect sand and fine gravel in the spring. I have to think there are some sort of contraction supply were you could buy sand. Also, there is PFS as an option. Look for those topics on the Substrate sub forum.
