Dumb question

[densa44]

I want to use a dry fly as an indicator and fish a nymph under the fly. I have been laying out a line for 70 years, wow where did the time go?

Here are the questions:

How do I ty the dropper and the dry fly on my line?
I use barbless hooks, I haven't kept a fish in over 40 years.

I would like to use either an elk hair caddis or a hopper as the indicator fly and it my attract a strike.

I have purchased, not tied a number of bead head nymphs that I'd like to try.

I don't want my line all tangled, or the nymph sinking my dry fly.

I'd appreciate all the help that I can get. I started off with a $10.00 glass rod from CTC that was so soft all I could do was make very short casts with my silk fly line and roll casts with a wet fly.
