Marine in Afghanistan Top and bottem end questions please help.

I have a 92lx 5.0 with about 150,000 miles on it still runs good but i want more power out of it. Long story short I bought the car when i was 16 with 80,000 miles on it in 2001 for $6500.00. I put BBK long tubes on it BBH off road H-pipe, Flowmaster 2 Chambers, BBK cold air intake, Venom 500 Control Box, and Roller rocker arms. Best run was a 14.20 at 102 with stock gears and bfg radials. Well i sold the car when i joined the Marine Corps, and got married and deployed to Iraq. I wish i would have never sold it. Well I am currently in Afghanistan and for a gift my wife tracked down the guy i sold it to and bought it back for $500.00!!!!!!! It is in perfect shape on the out side but the motor has seen better days and the t-5 and clutch are both destroyed. So I came got a new tranny for free from a friend who owed me alot of money to make up for some of the debt, New world class T-5 and other than that It needs everthing else. Also the guy i sold it to had the idea he was goting to turn it in to a drag car so he gutted the inside. Door skins head liner its all gone. and thats all he did beside try to run it into the dirt. So I have a very strict budget of $5,000.00. I can do all the work my self except the bottem end. So where do i start, I have seen alot of bottem kits on summit for decent price, has anyone every bought one and are they worth the money. And the bigest question I have is a top end kit???? I like the trickflow and the holley but, there just so expensive....... I know you get what you pay for but has any one peaced together there own kit and saved some cash. I have lookeed at the Patriot 185's and 165's fully assembled for under 900.00 are they compairable to any of the top end heads(edlebrock, trickflow ect) And also the upper and lower intakes mad by proffesional products look gread and are about $400.00 for both upper and lower. So are they compairable to any of the name brands? I also plan to up to 24lbs injectors with the matching MAF. Also a 70 or 75 mm throtle body which ever is required. But them with building my own kit like that, i am lost with what kind of cam to use. i know you can fill out a thing on cranes web site and they will recommend one. So I guess the question is build my own or buy a kit my end goal is 300+ rwhp and Alot more torqe. This car will only be driven once a week to work and maybe out on the town on saterday nights not a every day driver so nothing has to be geared to daily driver. So this is what i have to buy and found prices so far.
New door skins 350
head liner 100
interior trim 200
clutch kit 250
al. drive shaft 200

So thats already $1000.00 so only $4000.00 left. Is it do able or do i need to beg the wife to up the budget. But i want to keep it in this range. So any help would be great i can only get on the net when i am not on missions. So i cant do research on my own. Please help me. I cant wait to be home in 3 months drink a beer eat a steak and start pulling the motor the night i get home.

would it be a waste to do the top end and just leave the bottem end with 150,000 miles on it if i do a compression test and it seem good? or does it need a rebuild know matter what with that many miles.
