Mesomorph Weeks Advice on Calorie Intake\Muscle Gain

New to the forum, I'd like to introduce myself... my name is Brent.  I live in Northern California and I work with children with autism as well as attend college.  Have gone on and off working out my entire life, but I am ready to start taking it seriously...I figured a forum may help for support.  If you'd like to scan through this post (I tend to ramble, the important info is in bold, and questions are in italics)

A bit about myself...I am 5'8" and weigh 160 lbs.  I usually fall in the 167 range but I'm currently a bit light.  I recently joined a site on the net where you can track your daily exercise acitivies, as well as calorie intake and the software does some evaluations.  All in all the program is good, but I've certainly found some flaws.

Onto my question for you guys.  I set a goal to weigh 172 lbs by July 26 - a gain of 12 full lbs.  I would like to achieve this through muscle development and healthy eating.  

I am currently unaware of my % of body fat, I know that information would help with my questions and I'll try tomorrow again to get that information while at the gym.  

Few quick questions....

I am currently doing 30-35 minutes of cardio 3-4 times a week, as well as several miles walking several days a week.  I am also currently lifting weights three times a week.  In inputting all my food into the database over on that other site (not sure if we're allowed to post the name, some places consider it advertising) 

I have been keeping pretty good track of the food I eat, and today I consumed 1628 calories.  35% was fat, 31% was protein, 34% was carbs.  What do you guys think the appropriate percent of my diet should be protein?  I was thinking i should try to get that a bit closer to 40% than the current 31% if I intend to pack on muscle.


How many calories should I be eating a day?  I try to shoot for around 2000, sometimes I fall short.  


I have also inputted all activities I do daily into the site.  The cardio calorie counter seems to be pretty good, but sometimes it's hard to know how many calories you are burning while lifting.  Do you guys know of a way to better figure out how many calories you burn while working out?  I generally do about 6-7 sets of two different groups (ie, triceps and shoulders one day etc)  


When doing cardio, I understand the best method to *burn fat* is to do a 1:2 work\rest ratio while doing the cardio.  I generally get my heart rate up to about 150-165 while "working" and then down to 100 or so while "relaxing"  I know it'd be difficult to say exactly what type of cardio work out I should be doing without knowing my at rest heart rate, but can you guys comment on this?  I dont think I need to shave off *alot* of fan to achieve the body I want... I more so have to put on muscle so I'm not sure the fat burn cardio work outs are ideal for me.  


Please don't hesitate to post any relevant questions you'd like to know about me to further help your chances of giving me good advice.  Thanks alot guys, looking forward to getting to know the board.
