Re: Tips for writing solo's/improvising (scales)
The reason I strongly suggest you approach this from the major scale is that, approaching it from the minor pent is a flawed method that will only serve to further confuse you as you move forward. The pent minor scale is derived from the major and should be addressed as such. By making it your "foundation" you're setting yourself up for a very difficult and confusing musical journey. Trust me. I'm living this nightmare myself.
In short, if you learn the major scale and it's positions, you will then have ideas of what to play all over the neck.
If you want a simple excersize to help get your ears around this, try the following bit:
E----------4------5--------------------------------
B-----------------5--------------7------------------
G----------4--------------6------7--------------------
D----------4--------------6------7------------------
A----------4------5--------------7-------------------
E-----------------5--------------7-----------------
Now, play this scale over an A major7 chord.
Then play it over a B minor chord.
Next, play it over a C# minor chord.
Now try playing it over a D major7 chord.
And then an E7 chord
An F# minor chord
A G#diminished chord
and then your an octave higher on A major.
Here are the chords, just in case you're unsure.

Do NOT stray from the A major scale! Those 7 notes are all you need to play over all these chords! I know the particular scale form is not convenient, but this is about getting your ears to hear it first, and move the scales later.
Now, if you play these chords in succession, it will sound like a "chord scale." It's a very cool sound and is an awesome method of training your ear to hear different sounds which in turn leads to better writing, improvising and playing.
I know there is a lot of information here and that the tones are going to sound a little hokey at first. A little patience and discipline will go a long way!
The question you asked cannot simply be answered by "playing a new scale." If you can just get through this one little excersize, I promise you, new worlds of music will suddenly open up to you!
