Looking for secure offline wallet generation, also confused about address reuse.

I'm not really looking to buy anything with btc. At this point, I'm just trying to expand my portfolio to include crypto. So my plan is, when I add investment funds, I take 5% of the total and throw it into crypto.

The problem with leaving my crypto in coinbase is obvious. And since it's a buy-and-hold situation, I really don't need my key to ever touch a network until I want to sell. So I set up my FDE offline debian box with the bitaddress git repository, generated a paper wallet, and printed it to an offline printer.

Then I start reading more, and it's all "DANGER! PAPER WALLETS ARE INSECURE!"

One of the big ones they hammer on is address reuse. Am I supposed to hold every btc chunk I buy in a separate wallet? I'll have 80 different wallets to keep track of in 5 years time.

There's also been some concern expressed with regards to the algorithm itself, and I can see this. I don't particularly trust anything that hinges on javascript. So what can I use for offline generation of key/address pairs? I'm not looking for advanced mnemonics or anything else between me and the key (notwithstanding the AES on my backups.) I manage physical silver and gold, and key management is a part of my career.
