I am new to Guitar Talk on GuitarTricks forum. I'm 46 years old, and I stared playing a classical guitar about 1 year. I eventually want to buy an acoustic guitar; by I was told to learn on a classical guitar first. It helps to develop good habits. I do have an older Fender stat electric guitar, but I don't do any practicing on it yet. But I do play it once in a while.
The styles I like are classical rock, blues. I actually like a lot of the newer rock that come out from the 60’s to present. I don’t limit my tastes in music rock and blues; I like all types of music.

Up to now I'm able to form and switch the basic open chords fairly well. OK, I'm still working on better fluid switches but I am getting better.

Anyway, my biggest challenges at this point are:
1) Barre chords (Root 5, and root 6). I'm able to form the chords fine, but I'm not able to switch chords very quickly, or accurately. Is the any good barre chord strengthening exercises that can help me improve?

2) Strumming patterns. Is there anything available that shows you how to practice various strum patterns?

Any input will be well appreciated.
