No. the pressure are different, r22 runs at a fairly low pressure and you shouldn't be worried about blowing your gauges, but you won't be able to determine your super-heat or sub-cooling. for a about $100cdn you can buy the right gauges.
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
Always to the low pressure side. The low pressure side fitting is normally near the dryer ( large silver canister).
